FAQs - booking Puerto Rico flights

  • Are there any direct flights from Seattle to Puerto Rico?

    As it stands, there aren’t any airlines that are offering direct flights from Seattle to Puerto Rico. To get to Puerto Rico, you will have to deal with at least one layover during the journey. The airport in which you will have your layover depends on the airline you’re traveling with since each airline has its preferred destination. For example, when flying with JetBlue, there’s a high chance your layover will be at Boston or JFK, while all flights by United Airlines have their layover scheduled for Newark Liberty.

  • Does SEA have any airline lounges?

    Alaska, Delta, and United Airlines all have a lounge at SEA Airport. Alaska has three lounges in Concourse C, Concourse D, and the North Satellite, respectively. Concourse A hosts the Delta Sky Club and United Club, which can be found near Gate 1 and across from Gate A10, respectively. There is also a Centurion Lounge, USO Lounge, and The Club at SEA in the central terminal and south satellite.

  • Does SEA Airport have any onsite hotels?

    If you have an early flight from SEA, the best place to spend your night would be at Coast Gateway Hotel. This is the closest hotel to the airport, putting you less than five minutes from the main terminal. By staying here, you’ll be cutting down your commute, thus reducing any chances of missing your flight.

  • How do I get wheelchair services at SJU Airport?

    SJU Airport provides free wheelchair services to all passengers with limited mobility to help them get around the airport with ease. You can request a wheelchair at the airport information desk which is in Terminal B near the ticket desks. You can also reserve one through your airline so that it can be ready for you as soon as the plane lands. This, however, should be done at least 48hours before the scheduled departure time.

  • How does KAYAK find such low prices on flights from Seattle to Puerto Rico?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from Seattle to Puerto Rico.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from Seattle to Puerto Rico?

Top tips for finding cheap flights to Puerto Rico

  • Morning departure is around 3% more expensive than an evening flight, on average*.
  • When flying from Seattle, you will most likely depart from Seattle-Tacoma International Airport (SEA). This airport facilitates most domestic and international flights from Seattle, so you should ensure that you arrive at least two hours in advance so that you can have enough time to go through security.
  • When booking connecting flights, avoid those with a self-transfer option. These flights require you to check yourself and your bags into every individual flight, and that can be quite stressful and inconvenient.
  • Book a flight that lands in Aeropuerto Luis Muñoz Marín (SJU) as that is the main airport in the country. From here, you can get connections to virtually any region of Puerto Rico, either by air or by road.
  • While public transport is available from SJU Airport to the city center, you can’t use the bus if you have more than one piece of luggage. The best alternative, in this case, would be taking a taxi or hiring a rental car from one of the airport car rentals.
  • SEA Airport has a range of long-term parking options for anyone who wants to leave their car at the airport. However, you are advised to reserve your spot in advance so that you can have an easier time once you arrive at the airport.

I would have appreciated notification that our flight was moved to another gate LAST MINUTE so that we would not have missed it. We got no such notice and had to spend another night to catch an available flight in the morning, which was huge inconvenience. We will never fly Alaska again.

Liked premium seat. Did not like: having to pay for entertainment/wi-fi; having to pay for food; single-aisle; and, only three rest rooms.

The airline was way too cold. We were freezing, I don’t know if that is normal. Overall it was pretty good flight. Always flown Alaska Airlines and I am not changing.

I was sitting in row 31 and felt bad smell coming from the toilets especially when boarding and exiting not much during the flight.

Great. They got us on an earlier flight. Really appreciated that

I had very little legroom and the only food available was really salty

Offer snacks/meals for people with food sensitivities. HAVE TV SCREENS!

Cabin crew very friendly and pleasant. Flight left late but we didn't know why. Alaska Airlines app was not user friendly -- app wouldn't let us upgrade our seats, but no indication if flight was full. We wound up having to call the airline to request an upgrade and we were told none was available. Waste of time. Baggage retrieval was easy.

The boarding gate is literally just an aisle to the concourse. There is no seating and it's shared with several other airlines. It's crowded, hot, and standing-room only. It's difficult to hear gate announcements over the PA system with too many other carriers crammed into a small space. I've enjoyed flying AA in the past on the west coast, but the BNA single gate experience is horrendous! Never again from BNA to SEA with AA.

It was a partial full flight. But even with a spare seat it was hard to get comfortable More on me being a wide body probably

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

The walk from baggage claim to the taxi is very difficult for older people I will never fly into JFK again. It is physically challenging

Overall fine but both ways for this trip was delayed.

Flight was delayed by almost 5 hours. Suitcase was not loaded despite the flight being near empty (my colleagues’ suitcases did reach JFK, unlike mine). Had to argue on phone to get JetBlue to deliver the case to my hotel. Never again

The flight was excellent. The crew was welcoming and attentive.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Why does it have to be painful to fly long distances?

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

This is by far the worst experience I have had with American Airlines. The start of this trip was a complete disaster. I purposely planned my trip so that I would weather any delays so that I could make very important meeting at the Pentagon. My flight was cancelled because of maintenance and I was put on the first flight the next day but I was late to the meeting. After a long week at the Pentagon I just wanted to go home and my flight home which was early in the day was delayed. Eventually the flight was delayed until the next day. I was not authorized a hotel room because DCA was my point of origin. So I paid for a hotel out of pocket. The flight this morning was boarded then deplaned because the aircraft was hot. The flow of information was not happening in DCA and made it worse when the news was bad. I am going to take a break from American for my next few military flights. Hopefully whatever has been going on with American Airlines will be resolved.

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Missed this flight due to the first AA flight delay
