    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.

Your guide to booking Seattle to Puerto Rico flights

Get tips on when to book, when to fly and what to know before your trip.
  • If you can plan ahead, the sweet spot for booking your flight is 23 weeks before your trip. KAYAK data shows fares in this window are around 43% lower than last-minute bookings (made within 2 weeks of departure). Not ready to commit? Set a Price Alert and we'll let you know when prices change.
  • If your travel dates are flexible, book your trip for January when flights are typically cheapest and avoid December when prices are at their highest.
  • Flying on Saturday is usually the cheapest. Flights on Friday cost about 20% more on average, so being flexible with your travel dates could help you save.
  • If you're looking to save, San Juan Luis Munoz Marin Intl (SJU) is the cheapest airport to fly into from Seattle. If you have onward travel, don't forget to factor in the cost of your journey by train, bus or domestic flight.
  • Start your trip in San Juan, which is the most popular destination in Puerto Rico. From there, it's easy to continue on to other popular destinations such as Carolina, Fajardo and Rio Grande.
  • 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.

Delays. Again. Haven’t had a good experience out of Seattle in most flights. The flight was delayed and passengers were all bunched in one area even after the doors closed when there were tons of empty seats. Attendants chastised passengers for wanting to move and even embarrassed one man for telling him tons of the empty seats were actually premium seating and he needed to go back to the back of the plane the seats have been getting increasingly uncomfortable and the snacks are terrible if you get one. No options for people who don’t/can’t eat sweets. Prices keep going up and amenities and service keep dropping. Air travel has become more like taking a very expensive bus.

As a deaf person I appreciate the assistance provided by the boarding staff and the flight attendants.

WiFi did not work for the flight. Crew were polite but kept asking me to move my bag even after it had been moved to the preferred position previously and not moved since. I had a winter jacket as well and they changed their minds multiple times about where I was allowed to keep it.

Good seating and leg room. Able to choose seat. Nice crew, polite and helpful. Nice snacks. Meals have to be pre ordered, short flight do no meal required.

No complaints. Nothing for entertainment, but it's a regional smaller body aircraft, not a longer range long body. Didn't partake in any snacks, mainly slept for the whole short flight. Got me to A to B as intended.

I reserved exit row as I am 6’7” and was very disappointed to find out that my seats were as crammed together as the rest of the plane. Worse actually, as the seats don’t recline. I believe I paid an additional $200 apiece. What do I get for that? I guess it’s on me that I didn’t do the research to know this in advance but I’m tired of buying airfare which used to include an actual seat on the plane and now it is an additional charge. I think the seats I purchased are sold at a premium by deception by people like me that think these are desirable. Got forbid there’s an incident and passengers have to escape through these tiny passages. Love to travel but have to reconsider future trips because of the dishonesty of your industry. Have always had good experience in the past with Alaska but now I have soured. Thank you very little, Dean Jones.

Everything was fine, flight was on time. Seats are pretty comfortable. I paid extra for the extra leg room. Did not get food. The only thing I wish Alaska had was a seat back screen rather than trying to watch things on my phone.

The flight attendants stood there talking to each other instead of welcoming people on the flight.

My bag was gate checked in Seattle and I was told it would be at the end of the walkway when I arrived in Idaho. It was not and I had to get it from baggage claim. Southwest Airlines will gate check a bag even if they have room for it in the cabin. I like that a lot. Seattle Airport is not that easy to maneuver. Indianapolis is one of the easiest airports to navigate.

Truly, everything was professional, and extremely friendly with lots of smiles from all the staff. My only complaint is that both coming and going from San Francisco to Seattle and back the public announcement system on the airplane when I was sitting in the exit row was so loud that it hurt my ears, and I was not the only one I did report it to one of the stewardesses who thanked me and apologized, but truly Alaska Airlines is my favorite domestic Airlines by a far shot

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

They sent us to an airport way out of our way because they canceled our flight with no reason

I love no assigned seats and bags fly free. If Private Equity gets their way and forces Southwest to change they will be everyone else and I will stop being loyal to them. DON'T CHANGE YOUR BUSINESS MODEL!!!

Left GEG had the first flight of the morning and couldn’t leave due to broken plane then got redirected on to another flight which then I missed my connecting flight so they rescheduled my connecting flight then that one took off 3 1/2 hours late my 4 1/2 hour day turned into a 12 1/2 hour day

The people of SW Airlines really make it nice to fly.

More assistance and clarity for travelers with gate checking and lap children

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

Delta is the best. It was all very easy and on time.

Delay from Atlanta to Tampa was simply unacceptable. Multiple delays led to us landing after 3am. Worst travel experience of my life

I somehow thought my food preferences was saved to my account— everything had dairy and couldn’t eat anything.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Everything worked smoothly, never had a concern with the flight from start to finish.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

Premium economy was worth it. Great seats and good food.

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

I had to buy another ticket and you haven't reimburse me for it.

Wheelchair folks are great. Food not to my liking. Crew more interested in their lives than the passengers. Got the job done but just the minimum.

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

We did not have enough time to make our connecting flight. As a result, we were put onto a different airline for our second leg. The different airline was NOT comparable to British Airlines, and our arrival was significantly delayed. The actual flight on BA was amazing.

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.
