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.

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.

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.

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.

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.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

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.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

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!

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

Very well organized both boarding and deplaning. Very satisfied with the service I received.

Flight was on time arrived at the destination 10min early they kept in touch via email

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

Like the space, did not like the snack options, there was no power outlet in seats, no entertainment, no flyfi.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

For a four hour flight, I was disappointed that everything was for purchase except for coffee, tea, or water. The disembarking in Iceland was so inefficient and time-consuming. We landed and stopped in the middle of the tarmac, had to disembark in the rain, and then squeeze into a bus which took us to the airport. Crazy! How does that work in winter?

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

I had an exit row and so was Comfortable on the long flight.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

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

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

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.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

Everything OK , except the plane left more than an hour late so I couldn’t participate in an excursion I had that morning in Brcelona

Great flight, short and good attention. Didn't took any food so can't say thing about it

A 13 hour flight with no food apart from what they offered from a menu you had to pay for. On top of that, there were no blankets, so during the flight when the cabin temperature dropped, everyone was very cold. Neither of these things were highlighted at the time of booking. This is the worst long-haul flight I’ve ever encountered.

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Personal at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

Only for BA because we had to get to Edinburgh at a certain time. Baggage lost, late boarding with only one person checking, again, our passports and boarding passes until the despatch controller had to step in to get us away. Will never fly BA again.

The food was very good and it came multiple times

Flight from LGW to JFK delayed by 4 hrs No explanation given until the pilot said the delay due to planned maintenance on the aircraft

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

CONSTANT ERROR MESSAGE THAT THE WIFI COULD NOT BE PURCHASED DUE TO INABILITY TO CONNECT PAYMENT SYSTEM VIA SATELLITE. THIS HAPPENED IN BOTH DIRECTIONS. THE MAIN REASON I TRAVEL IN PRIORITY IS TO BE ABLE TO WORK FOR WHICH I NEED ACCESS TO INTERNET. .

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!

Waited 3.25 hours in plane only to have the flight cancelled.

The business class seat was an uncomfortable conversion of a main cabin seat well below the quality of even the budget carriers in the US. I would have never paid for business class if would have known I get the same seat as main cabin. BA has gone down hill significantly in this class of service.
