FAQs - booking Puerto Rico flights

  • Which visa should I get for travel to Puerto Rico?

    A US ESTA and a valid passport are necessary for UK nationals on flights from the UK to Puerto Rico, allowing for stay of up to 90 days. Online applications are processed in about 1h at a cost of approximately $22 (£10.50).

  • What’s a recommended transport method from Luis Munoz Marin International Airport to downtown?

    Some convenient transport options from Luis Munoz Marin International to Old San Juan are taxis, airport hotel shuttle transfers, car hire or Uber rideshares. There is public transport available to the city centre, but luggage is not allowed on board.

  • What car hire is available at Rafael Hernandez International Airport?

    Avis/Budget, Hertz and SIXT are three providers you can find at the onsite car hire centre, after your flight from the UK to Puerto Rico arrives at Rafael Hernandez International. There are also a few others at offsite facilities nearby, and most offer optional child seats, if you’re travelling on holiday with the kids.

  • How can I get a direct flight from the UK to Culebra?

    Isla Culebra is a small island off the east coast of Puerto Rico. Unfortunately, there are no direct flights available to Benjamin Rivera Noriega Airport (CPX), but JetBlue does provide flights from Heathrow with connections via New York and San Juan.

  • Which London Airport offers flights from budget airlines?

    If you're flying from London to Puerto Rico, you can generally choose between London Gatwick (LGW) and London Heathrow (LHR). Gatwick Airport often has cheaper flights available, as they have more low-cost airlines operating out of their terminals. Bear in mind that this usually also means a smaller luggage allowance.

  • Which London airport is closer to central London?

    Heathrow is closer to Central London, with the Express train taking around 15 minutes from London Paddington. Gatwick's Express train takes about 30 minutes from London Victoria. It usually takes about twice as long if you take non-express trains, such as the Elizabeth Line to Heathrow.

  • Where are the car hire desks at Luis Munoz Marin International Airport?

    You can find the car hire desks, including Hertz, National and Enterprise, just across the street from the main terminal. As you exit the Baggage Claim area, head straight across the road to the parking garage. You'll find most car hire companies on the First Floor and some, such as Alamo, have self-serve kiosks available, making it extra easy to pick up your vehicle. Most vehicles are located on-site, so you can start your journey in Puerto Rico right away.

  • Are car seats required for children in Puerto Rico?

    Child safety seats are required for children under the age of four, and children between four and nine must use an appropriate booster seat. Booster seats are also required for children who are under 145 cm tall. Most car hire companies can provide child seats. However, while car seats aren't required in taxis, some rideshare drivers may refuse to take children without an appropriate seat. Not all taxi services will be able to provide a car seat, so consider bringing your own if you're planning on using taxis frequently.

  • How should I get from Rafael Hernandez International Airport to Aguadilla?

    There is no public transport available for passengers arriving at Rafael Hernandez International Airport (BQN). However, you will find taxis and rideshare drivers readily available, and the drive into Aguadilla usually takes around 20 minutes. You can generally expect to pay around US D20 (roughly INR 1,645) for the trip from the airport to Aguadilla's City Centre.

  • Where are the car hire desks at Mercedita International Airport in Ponce?

    You can find the car hire desks at Mercedita International Airport in the main terminal. Most desks are located near Baggage Claim and the vehicles are usually a short walk from the terminal. You can find a number of different companies including Avis, Enterprise and Thrifty.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United Kingdom to Puerto Rico?

  • The Caribbean island of Puerto Rico has several airports supporting flights from the UK. The primary one, Luis Munoz Marin International (SJU), is located in the northeastern capital of San Juan, and the other main one, Rafael Hernandez International (BQN), serves the western coast of the island. Antonio Rivera Rodriguez Airport (VQS), on the island of Vieques, is another major destination for flights from the UK to Puerto Rico.
  • A number of airlines offer one-stop flights leaving London’s Heathrow Airport (LHR) to San Juan. Lufthansa heads the list, with substantial service connecting at Madrid, Orlando or Philadelphia. If you’re flying with Iberia, British Airways or American Airlines, your connection will most likely be in Madrid. Two-stop service is the preferable choice available from Birmingham Airport (BHX) to San Juan. KLM, Aer Lingus and Air France all provide flights via Amsterdam, Dublin and Paris, with final connections at New York JFK.
  • To arrive at Aguadilla from London, United Airlines provides frequent flights departing Heathrow with connections at Newark, Orlando or Washington, DC. United also provides flights from Manchester Airport (MAN) via Frankfurt or Brussels and Newark, but you can also fly aboard Aer Lingus with a single connection at JFK.
  • Vieques is a popular tourist destination off Puerto Rico’s east coast. You can get flights there from Heathrow via JetBlue, with connections at New York JFK and San Juan Luis Munoz Marin International. Aer Lingus departures from Manchester to Antonio Rivera Rodriguez Airport also involve stopovers in New York and San Juan.
  • Passengers travelling to Heathrow from Central London can get Heathrow Express trains from London Paddington Station. The airport’s rail station also accommodates Network Rail trains from UK cities, while its bus station supports National Express coaches. Heathrow Terminals 2-5 are linked to the London Underground via the Piccadilly Line.
  • Although flights from London to Puerto Rico are usually the cheapest, Manchester Airport (MAN) is a good alternative for travellers departing from Northern England. You can find one-stop flights to San Juan (SJU), Ponce (PSE) and Aguadilla (BQN). These flights commonly stop at Orlando International Airport (MCO) and JFK International Airport (JFK) in New York.
  • If you're flying to Puerto Rico from Scotland, Edinburgh Turnhouse Airport (EDI) is a handy departure airport. From this airport, multiple airlines offer one-stop flights to Aguadilla and San Juan.
  • Bear in mind that if you're flying to Puerto Rico from another major UK airport, it may sometimes be cheaper to fly to London or Manchester first, before taking a connecting flight to Puerto Rico.

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

The staff were all particularly great. The plane was clean and fresh. The bassinet worked great. It was all very nice.

Friendly crew. Poor food service maybe due to full flight. All in all, you get what you pay for.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

They have the most inexperienced / rude flight staff I’ve encountered

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

JetBlue is always consistent and great, the food is limited in selection, but at least you can grab as much as you want on snacks and drinks at the Blue Locker.

You get what you pay for with JetBlue. Every little thing costs more, you are nickel and dimed until the end. Entertainment doesn’t function. Flight attendants do the bare minimum.

The check in and boarding process was a bit of a cluster. Two people at the counter to check in, three random lines that nobody knew which was for what, and people kept getting shuffled from one line to another for no apparent reason because then they’d get shuffled back and end up getting out further back in the line than they were originally. I only had to hand my already checked bag over and it took 45 minutes. I was never assigned a seat so when I tried to board I was pulled out of line again while someone had to try to manually assign me a seat. During the flight I got up to go to the bathroom, and there was an attendant in the aisle offering pillows etc and it was a 30 min wait unbuckled standing by the bathrooms because she said I couldn’t go past her. First and last time flying jet blue to be honest.

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Never again. Terrible hospitality and human decency for an international flight. No food, no snacks, no beverages, blankets, pillows, limited entertainment. Tiny seats without any cushion and some do not even recline. I was shocked that they did not charge for seat belts. Never in my life have I witness asking for "spare change" for charity before landing on both legs of the flight. Icelandair can contribute on their own to said, so called, children's charity with the money saved from providing 3 centimeters of tea and water to hungry and dehydrated passengers.

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

They had a 4 hour delay and left my luggage in Iceland and it didn’t arrive in Portland until 11/1

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

Service was excellent. Food and drinks were very good except for a greasy lump of a donut at the end of the flight that left us both feeling internally disgusted.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

Flight to get to Barcelona was cancelled and then the next flight was overbooked. Cancelled the entire trip and went elsewhere. Fighting with iberia to get my money back. Ill never book this carrier again!

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

Difficulty to check in online, but well handled at the airport. Flight delay was unfortunate. Crew was adequate but not what we have usually experienced from BA. Seat was not comfortable.

Arrived on time. Great crew. Good food. Luggage delivered promptly

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.

I have nothing but great things to say about the crew of the American Airlines flight from Madrid to Dallas. They were fantastic! I do, however, have some disregard for the flight attendant that was late in Dallas, causing us to further delay the boarding of our flight to Portland, and leading to the eventual cancellation of that flight. Because that crew-member was so late, we got caught-up in a weather-related ground stop, eventually causing our pilots to "time-out". So we couldn't get out of Dallas. We would have departed DFW on-time (and before the arrival of the thunderstorm) if not for the lateness of that crew member. The whole time the pilots couldn't tell us whether the flight would be cancelled, and that they couldn't get any information from the airline. By the time we knew the flight was cancelled, all of the flights for the following day were full. So, we didn't even get offered a viable option to get home. The American Airlines customer service desk at DFW was grossly under-staffed. And there were several people who waited in line for four-hours before being helped at that desk. We waited in line for almost 2-hours, until I was able to speak with a customer service agent on the phone (after being on-hold for over an hour). So, once we knew the information about how to get our bag in PDX, and that there weren't any options for flights the next day, we left the line & began searching for another way home. We eventually had to purchase a ticket home on a different airline, in order to get my wife to work on Monday. And we are pursuing a refund of that DFW-PDX leg of the journey. The good news is that the late flight attendant's hair was perfect. And she looked fantastic as she departed the airport & headed back home, while we all hunkered down to sleep in the terminal for the night.

I liked the comfort of the plane. It was unexpected from past experiences.

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights

Logan gate staff was unhelpful. Arrived early, come to find out the airbus scheduled was reassigned and I did not have a seat. The desk agent spoke to his supervisor who instructed him to give me a boarding pass to get up to gate area, he was polite. At the gate the fellow was sitting to the side with two other BA staff . I asked him if he could help me, his answer was” we are on a break, we are closed” then turned his back. I am almost 70, drove 4 1/2 hours to Boston and had been looking forward to this trip for 5 months. I have worked in service many times in my life and this is not how it is done. I eventually (1/2 hr) before boarding was able to get a seat. The rest of the flight experience was unremarkable.

The boarding process was very poorly organized. Too many people had way to much carry on and resulted in loading overhead bins being the gating factor. Time for change.

The boarding process was chaotic at LHR and the seat was not as comfortable as other airlines....

Everything, every step of the process, from check in, to boarding, to exiting the plane was organized, efficient, and orderly. Excellent experience!

Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.

We always use BA due to the direct flight options, we have always had a pleasant flight with BA.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Unfortunately, my flight was cancelled because of some sort of emergency over the Atlantic and had to return to London. While I think British Airways made every effort to mitigate the situation, I must say it was still pretty unpleasant. I do appreciate the fact, however, that British Airways put my safety first…and I think the effort to correct a bad situation was very sincere. But I think the process might be handled better in future.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience
