FAQs - booking Puerto Rico flights

  • Do I need a car seat to drive in Puerto Rico?

    In Puerto Rico, children under 12 years may not sit in the front seat. If your kid is between four and eight years or has a height of fewer than 57 inches, you are legally required to place them in a booster seat. A child safety seat is mandatory for children under four years.

  • Do I need a visa to visit Puerto Rico?

    UK citizens need a visa to travel to Puerto Rico. It may take up to five days to acquire the visa, so be sure to start the application process a few days before your flight. Note that the Puerto Rican Counsel has the discretion to offer visas or not.

  • Which airport is closest to El Morro Fort?

    If you are in Puerto Rico to explore the remarkable beauty of the centuries-old El Morro Fort, consider making Luis Muñoz Marín International Airport your arrival point. You can take a taxi to the fort and arrive in roughly 30 minutes. If not in a hurry, taking a bus is more fun. Buses go as far as Cataño, where you can take a ferry to El Morro Fort.

Top tips for finding a cheap flight from London to Puerto Rico

  • Morning departure is around 17% more expensive than an evening flight, on average*.
  • London Heathrow (LHR) is the departure point for some of the cheapest flights from London to Puerto Rico. The airport is also an ideal place to board your plane as most airlines for the London-Puerto Rico route start their flights here. Further, it is an excellent place to treat yourself to shopping therapy, having been voted the best airport to shop for several years. Other departure airports include London Gatwick (LGW), London Stansted (STN), London City Airport (LCY), and London Luton (LTN).
  • At the moment, direct flights from London to Puerto Rico are unavailable. Thus, consider selecting a flight route with a stop in a city you would love to tour. Possible stopovers occur in major US cities such as Miami, Charlotte, and Boston. Trips may feature at most two transfers. Note that one-stop flights are cheaper than journeys with two stopovers.
  • At the end of your journey, you may arrive at any of three major airports in Puerto Rico. Most flights arrive at Luis Muñoz Marín International Airport (SJU). Given its accessibility and proximity to San Juan, the airport is an excellent arrival point for travellers who wish to tour Eastern Caribbean. Additionally, the airport is ideal for sightseers travelling to cities like Bogota and Panama. The other two airports, Rafael Hernández Airport and Mercedita International Airport, are favourable for those planning to tour the Northwest and South parts of Puerto Rico, respectively.
  • Being a large city, most London airports are usually busy and feature long queues at security checkpoints. Notably, London Gatwick has shorter lines. The airport has automatic gates, which keeps delays low. However, the airport opens its boarding gates a few minutes before departure. If you arrive too early, you may have to spend some money dining in its on-site restaurants.
  • Touring the numerous attractions in Puerto Rico is more fun with a rental car. At Luis Muñoz Marín International Airport, the car rental centre is on the first floor of the terminal building. Similarly, you can hire your preferred vehicle type at Rafael Hernández Airport at the counters located in the Baggage Claim area. If you arrive at Mercedita International Airport, rent a car in the terminal building near Baggage Claims.

All good- I love BA and the professionalism of the crew and pilots.

All good- I love BA and the professionalism of the crew and pilots.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

Very rude hostess. She embarrassed me in front of others. I went to sit after taking off in a different sit in the same economic cabin. Was the area where doors are. She come to me very laud and said: go back to your sit those sit are more expensive.wow! No diplomacy. Flight was super full except 3 of those sit. The only person in that row later during the flight occupied all sit laying down!. Once more disappointed at American Airlines. Early flight they lost my luggages for 4 days. Never refund money for replacement for some of essential items purchased..when I booked the flight I thought was Finlandair. I

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff were fantastic friendly nice they came round and check we need anything else to eat or drink

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff for a fantastic friendly nice we came round and check we need anything else to eat or drink

From the start everything was perfectly fine. First meeting was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast.

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

We liked the flight, but not in JFK, not in Gatwick it is no lounge and this was surprising and disappointing. I think by now it is understandable that COVID will not go away and why it should not be business lounge?

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

Realize ahead of a 6:30 am flight that you have a completely flat tire that needs replacement. They should have never boarded everyone. They kept us at the gate with the door closed for ALMOST but not quite 3 hours. The plane had been sitting there from the night before. At the 2 hour mark of sitting there, they came through with a bottle of water and cups. Never offered snacks. Never offered a real apology. People missed connecting flights completely. Absolutely no apology. Just yep you are going to miss your connection completely. I don’t know if you can get to your destination today. The new boy time there was a seemingly heartfelt apology was when they said they were sorry and then fifer everyone an opportunity for a credit card. It was so poor. Lucky for us, our funeral was not the same day as our flight or we would have missed it. All for an avoidable repair that could have been done before we even set foot on the plane.

None of the in flight Direct TV worked. A better selection of Shows would have been better. The baggage was s low. Otherwise we enjoyed our flight!

Wifi screens were great. Both flights were delayed, spending all day flying home and then getting home at 3am ruins the next day also.

The seat was visibly dirty, had not been cleaned. I used my own wipes and they were dark after wiping down the chair and tray table.

They never came by to take empty cups or trash.

I paid for premium economy but BA oversold the seats and we ended up being downgraded. Not acceptable given how much we paid for the flight. We were also separated to 2 different areas so not only did we not get the service we paid for, we didn’t even get to sit together. I’m not happy at this treatment by BA because of corporate greed.

Original flight was cancelled - After waiting 2 hours for new take-off times. Then had to stand in line for 3 hours, ending at 2:30 am - to be told, " No hotel rooms anywhere in Dallas". No way for me to get any rest at DFW at that time of night.

Thankful for 2-4-2 economy seating. Food was ok. Free beer & wine in economy was nice. Served hot dinner, mud- flight snack and pre-arrival ham sandwich. Seat with pillow & blanket. Reasonable movie options. Overall, a good experience. IBERIA APP is terrible terrible terrible.... needs to get upgraded to equivalent of TAP Airlines App. No option to bid or request an upgrade. Very disappointing.

Boarding process was chaotic and disorganized. The plane needs updating in the interior. Things are broken, worn out, and dated

My luggage did not get to my Miami destination/home. I am waiting for it 24 hours later.

Flight was delayed by well over an hour. Communication was terrible.

Fast check in, easy to navigate, crew were very good, the plane was delayed due to a previous flight and I found the cleanliness a little lacking but overall it was fine

I like the team but I don't like the food you provided with money. I want free food and free water.

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

Air hostess delayed providing food and then pulled away the tray before i finished eating

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.
