Flights from Seattle to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Seattle to the United States 
Verified travelerFlew with Alaska AirlinesSEA-DENMar 2025
Alaska Air is very efficient & on-time so allow enough time to get luggage, go thru Customs & Immigration, & long security lines. Terminals in SEA are readily accessible by trains but more signage is needed. Fortunately, Information booths are everywhere & are manned by very helpful staff.
Verified travelerFlew with Alaska AirlinesSEA-CLEMar 2025
If you have a rental car, give yourself time to catch the shuttle to the airport. Also be aware traffic is awful and will often be standstill on the way to the airport.
Verified travelerFlew with Korean AirSEA-PDXApr 2025
Alaska airlines is more convenient and better than Delta when flying from SEA to PDX. They have many more flights and great customer service.
AngelFlew with Alaska AirlinesSEA-ABQMar 2025
Fly into a different city with more options for departure times. Not to have a six hour layover.
ShuraFlew with Alaska AirlinesSEA-BURApr 2025
Don’t . Delta has all the gates together for easy transfers and much more food and beverage selection
Verified travelerFlew with Alaska AirlinesSEA-ATLMar 2025
Regardless of the shortage it has, yet Alaska Airlines is the best
Verified travelerFlew with Alaska AirlinesSEA-PHLApr 2025
Direct flight is worth the cost. Use the app. Fast and smooth.
MichaelFlew with DeltaSEA-DENApr 2025
Train from Denver airport to downtown is easy to use.
JanFlew with Alaska AirlinesSEA-ANCApr 2025
Again snacks unless you want to eat prior or order ahead of time for flight. Wear layers as usually warm or as my case a little cool.
RobertFlew with United AirlinesSEA-SFOMar 2025
If you’re picking up a rental car it’s not very clear that you have to take the train. Signage can be improved at SFO.
Verified travelerFlew with Alaska AirlinesSEA-PSPDec 2024
Be courteous of your fellow travelers. Remember the carry on baggage rules. Keep your jackets out of the storage bin on full flights. Don't move other people's luggage from one bin to another. Step out of the isle as quickly as you can. Be sure you're in the seat(s) assigned to you.
TonyFlew with Alaska AirlinesSEA-ATLDec 2024
Delta, definitely Delta. Stop charging for checked baggage, when you ask people to check it for free at boarding.
Verified travelerFlew with Alaska AirlinesSEA-GEGDec 2024
I only fly Alaska to Seattle and on to Spokane most of the time. Always good!!
ROTKEOFlew with Alaska AirlinesSEA-ONTDec 2024
Alaska Airlines has always been great to fly in and out of Seattle.
Verified travelerFlew with Alaska AirlinesSEA-SBAJan 2025
Alaskan Airlines has a good flight schedule to Santa Barbara every day.
Verified travelerFlew with Alaska AirlinesSEA-DENDec 2024
I didn’t have any problems using Alaska Airlines
Verified travelerFlew with Alaska AirlinesSEA-PDXDec 2024
The flight landed delayed and missed my flight. I had to rent a car to make it back home
Verified travelerFlew with Qantas AirwaysSEA-LAXNov 2024
Alaska and Delta by far have the best service from Seattle to LA, with many flights a day. I honestly prefer Alaska in general, but they codeshare so much with American, whom I generally loathe, that I have been switching my flying to Delta simply to avoid American. American themselves run 2 CRJs a day via SkyWest to LA, and United runs one or two flights as well. The American service is what it is — I only took it due to a vastly lower price for a Qantas ticket to Australia.
ReidFlew with United AirlinesSEA-LAXOct 2024
SeaTac does not have a very good or equitable system for security lines. First class passengers don’t have a TSA precheck option, while there are only 2 TSA precheck lines on opposite sides of the terminal. Highly recommend getting TSA plus Clear, as the airport heavily favors this combination, with each section of the terminal having one of these options. I almost missed my flight because the only TSA precheck line was about 45 minutes long.
Verified travelerFlew with Alaska AirlinesSEA-MCIOct 2024
TSA lines in Seattle can get very long early in the day. Also, plan to return your rental car early since you have to take a shuttle bus to the terminal and those lines can get long early in the day, too. Currently there is construction in the North Terminal, so be prepared for moving around barriers. The day I flew out, the escalators were not working.
BarbFlew with DeltaSEA-MSPSep 2024
Try not to get to the airport too early. We came off of a cruise and had a 6 hour wait. Unlike MSP, SEATAC didn’t have free WiFi. But, McDonald’s did. And the three hours before the flight we used the Delta Lounge which is always amazing.
DanaFlew with Alaska AirlinesSEA-MKESep 2024
That was my first time flying Milwaukee to Seattle & vice versa. I think we choose a good airline. Seattle’s traffic & airport is busier than Milwaukee so get there at least 2 hours early. Download & keep an eye on the Alaska airline app for flight info updates.
Verified travelerFlew with Alaska AirlinesSEA-HNLSep 2024
Bring your own food or eat before boarding. Get to that airport 3 hours early for a domestic flight, the TSC screening line was 45 minutes long and if you have to walk to the other side of the terminal you might have to run.
BrandonFlew with Alaska AirlinesSEA-INDOct 2024
Arrive to the Seattle airport much earlier than you would the Indianapolis airport. This might be obvious, but the Seattle airport is much larger than the Indianapolis one.
Verified travelerFlew with Alaska AirlinesSEA-CVGSep 2024
We chose Alaska as they flew non stop from Seattle to Cincinnati and back to Seattle. A bonus not to stop in Chicago.
Verified travelerFlew with Alaska AirlinesSEA-OMAOct 2024
Get past the tsa employees and you will find caring attendants who are attentive to your needs with the Alaskan Airlines employees!!!
KrisFlew with Alaska AirlinesSEA-GEGOct 2024
Spokane's Alaska boarding area is lovely! You will be welcomed warmly once you get off the plane.

SeaTac lets you make an appointment to get through security. SpotSaver. No cost. Online.
KimberleyFlew with Alaska AirlinesSEA-OGGNov 2024
Pack snacks and patience. Ear plugs or noise-cancelling headphones are a must!

JessicaFlew with American AirlinesSEA-DFWSep 2024
Use Seattle's Port Vallet! It was SO worthwhile!
BruceFlew with Alaska AirlinesSEA-LAXNov 2024
Tight interline connection at LAX - barely made the flight. Directions from AS arrival gate to separate AA commuter terminal for AS codeshare flight connecting to TUS would have been nice.
JoanFlew with Alaska AirlinesSEA-JFKNov 2024
SeaTac should add sand to the painted floor from the terminal to the light rail. It is VARY slippery when wet and the northwest (Seattle) is known for rain.
Verified travelerFlew with Alaska AirlinesSEA-ELPOct 2024
It’s a long flight but very comfortable. Too: don’t ask for decaf coffee. Would have liked better choice of snacks. Otherwise it was a fine flight.
Verified travelerFlew with Alaska AirlinesSEA-DFWOct 2024
Long train ride in Dallas to gates, but pretty easy to navigate, no real issues
StephenFlew with Alaska AirlinesSEA-RNOOct 2024
Buy food in the larger terminals. Gate S was an outpost
Verified travelerFlew with Alaska AirlinesSEA-CMHSep 2024
Seattle airport is a nightmare. Too much construction leading to confusion where to go and poor signage. Really crowded airport and waiting areas. Trying to get large fully loaded suitcases on escalators is ridiculous. Someone is going to get hurt. Columbus airport much easier to navigate and less crowded.
Verified travelerFlew with Alaska AirlinesSEA-MCOOct 2024
Orlando airport is excellent. Seattle - not so much. Alot of chaos in Seattle.
Verified travelerFlew with Alaska AirlinesSEA-SATSep 2024
Better training for your waitress in first class..
ShirleyFlew with Alaska AirlinesSEA-ORDJun 2024
I generally fly United or Delta out of South Bend, IN into Seattle or wherever I'm going. I have no issues with Alaska. I only use Alaska when flying with my family from the Seattle area back to Chicago O'Hare and then we drive to SW Michigan where I live. Alaska Airlines has a beautiful new terminal at SeaTac as well. A good airline. I do like planes that have screens on the back of the seats.
Verified travelerFlew with Alaska AirlinesSEA-BOSJul 2024
Generally Alaska Airlines have very friendly and helpful people in my experience. They don’t have TVs in all planes so make sure to download their app if you want entertainment on the plane.
KimberlyFlew with Alaska AirlinesSEA-SNAJul 2024
When going to Disneyland fly to this airport. Only 8 miles from Disneyland and super quick to check in and check out. Highly recommend this airport!
KateFlew with Alaska AirlinesSEA-CMHAug 2024
Get to the airport early. It’s much busier than the Columbus airport. It’s worth going earlier so you aren’t anxious about missing your flight.

bring wireless earphones and chargers. you have to use your own phone if you want to watch movies or tv onboard.

They will not wait for anyone so make sure you are there with plenty of time to spare
Verified travelerFlew with Alaska AirlinesSEA-BURAug 2024
Burbank Airport is the best place to start your travels: small airport, short lines, and easy check in.
Verified travelerFlew with Alaska AirlinesSEA-JFKJun 2024
Fly with an airline that you know has tv's. Without a form of entertainment this flight is brutal.
Verified travelerFlew with Alaska AirlinesSEA-INDJun 2024
Get to the airport with plenty of time before your flight. Sea-Tac is one busy airport!

Budget if you’re planning on shopping for meals or souvenirs at Sea-Tac, it’s not cheap.

Unfortunately Southwest seems to be the best with no charges for the bags..atleast in 2024
Verified travelerFlew with Alaska AirlinesSEA-PHXJul 2024
Seattle is a busy gate. Find your gate first as connections may involve underground tram.

I wish you had movies like delta. Especially on long flights. On my flight to Seattle I didn’t pay more for row 15. On the fight back when the 3 rows were empty I asked if I could sit there. I was told these are more expensive. Wouldn’t it be better to make the customers more comfortable, than leave empty seats ?

LAX is a bit of a mess. Very long walk between terminals.
Verified travelerFlew with Alaska AirlinesSEA-DENMay 2024
When flying from Seattle to Denver, be ready to take our any electronics and put them in separate bins when going through security. You will also most likely have to take off your jacket as well. During our flight back the flight randomly changed so be on the lookout in case that happens to you! It was by chance that I checked my ticket and saw that the gate changed last minute.
ElaineFlew with Alaska AirlinesSEA-PHLMay 2024
If you have any metal in your body (e.g., spinal fusion screws) make sure you get in the line for the TSA security screening booth that makes you stand on the yellow marks with your arms over your head. I wish I had known this before I wasted time in the alternate line with the walk-through detector.

Alaska did great. By comparison my son and family went to Disneyland on Spirit and will avoid Spirit at all costs in the future.

I don’t know is it exist on Boise airport, but Lufthansa and United are good and even for a huge distances like to travel between continents, they fly smoothly. Alaskan hurry up to come faster, but faster it can not be safer, you can experience all the shaking and suddenly blood pressure from going suddenly fast to high altitude and who have a heart problem or pregnancy put himself under a big risk flying with Alaskan airlines.
MelissaFlew with Alaska AirlinesSEA-HNLMay 2024
Bring your own snacks because they will not feed you any kind of a big meal and it’s five hours. It’s a long time to wait without food. You do get a pretzel bag and a cookie and two drinks but that’s not enough.

Alaska is a great airline and price is great, but be flexible on time. Pack a lunch and bring a water bottle to fill up beyond the check point…

I made a mistake. Read what I wrote in the flight from Dulles to SEA. The negative experience was from SEA to BOI. Total garbage. Wont do it again.

I made a mistake. Read what I wrote in the flight from Dulles to SEA. The negative experience was from SEA to BOI. Total garbage. Wont do it again.

Need to get on train for second flight it’s much nicer when all the gates are together for obvious reasons

Cramped, crowded aircraft. Poorly organized boarding. Tasteless crackers to eat. 40 minutes late. A standard US air travel experience.

Would not mind having movie options an available like Delta, but is not necessary. Did not have food, so cannot appropriately rate that section.

Three hour flight so snacks and basic drinks unless you pre buy as usual. Didn’t do my emtertainment as was tired after 23 hours of travel. You have to use your own device on US flights if travelers aren’t aware so if you only use your cell phone that can be small. Crew are great.

Awful. We got the last seats and they don't recline. We've been on this horrible journey since 6am and won't get to our destination almost a full day later. Oh and no food, either. Never again.

An uneventful flight is a good experience although one of the pilots gauges wasn’t working right so we had a half hour delay—no one can foresee that.

Plane was delayed and got me in past bedtime. But more importantly, my tsa precheck number wasn’t on my ticket so had to deal with the general line. Oh well, guess the delay helped that situation.

It was as good as flying can be, which is still very uncomfortable. Clean new aircraft, great crew.

Everything was good. The flight attendants were great. I was disappointed that there wasn’t any screens on the back of the seats to watch movies, tv, etc. I only had my phone to watch movies on.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

A bit rush for transit. Food and entertainment are not available

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

leg space better than expected. two washrooms for one plane isn't enough.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Took off on time and successfully avoided weather that looked to be a problem along the way

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

The reps working at the airport counter were dumber than a second coat of paint.

My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

The worst flight of my life. Never will I fly frontier again
