Flights from Seattle: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew from Seattle to anywhere 
Verified travelerFlew with Alaska AirlinesSEA-STLJul 2025
Give yourself extra time. Love the self check in options.
KeithFlew with IcelandairSEA-KEFJun 2025
The boarding was good but the line for check-in is pushed off to the side because of the recent construction. It’s fine but cramped as people jostle to get checked in. Also, we weren’t able to use our online check in and printed boarding pass so we had to basically check in twice.
KimberlyFlew with DeltaSEA-FLLJul 2025
Ask for headphones to watch screen movies as all of mine are bluetooth and that will not work. Bring own food and wait until plane moves before hooking up to Deltawifi.
Verified travelerFlew with Hawaiian AirlinesSEA-ONTJun 2025
Make sure to be there on time because the bag drop off can be a little complicated and it takes quite some time to get to the gate.
Verified travelerFlew with Alaska AirlinesSEA-MKEJun 2025
Order ahead or bring own meal on plane
Verified travelerFlew with FrontierSEA-PHXJun 2025
Wish I had known the seats were so uncomfortable. Wish I had known checked bags and carry on bags were 75 each. Wish I didn't have to wait so long in line with only one clerk working. Wish I had known we were going to have to take a bus from the gate to our airplane. Wish I had known the seat space is smaller than any other airline I have flown. I do not recommend Frontier.
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.
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-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 EVA AirSEA-TPEMar 2025
Arrive early at the airport. Bring personal items like toothbrush and toothpaste if needed because it’s a long flight. If you’re flying with Eva, I don’t think you’ll need more than that.
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.
SuzetteFlew with Alaska AirlinesSEA-IADMay 2025
Take a shower before arriving at airport and don't wear perfume at all! Pack bags tight, so boarding is smooth and quick.
DanielFlew with Alaska AirlinesSEA-IADMay 2025
Seatac has gnarly traffic right now, took 35min to get from highway exit to the terminal
Verified travelerFlew with British AirwaysSEA-LHRApr 2025
Make sure you have plenty of time between flights if you are delayed.
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.
Verified travelerFlew with Air CanadaSEA-YYZJan 2025
Be careful about directions. Best to ask representatives about proper gate.
Verified travelerFlew with Alaska AirlinesSEA-ONTOct 2024
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!
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.
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.
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.
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.
StephenFlew with Alaska AirlinesSEA-RNOOct 2024
Buy food in the larger terminals. Gate S was an outpost
KathyFlew with Alaska AirlinesSEA-HNLSep 2024
Bring warm clothing, a blsnket, your own water to keep hydrated.
DeeFlew with Alaska AirlinesSEA-DFWSep 2024
Arrive early as repairs and construction underway at Seatac.
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-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.
Verified travelerFlew with Alaska AirlinesSEA-BNAJul 2024
Fill or buy a bottle with screw on cap with water for flight. If you have to get up and down it can be placed behind the seat in of you.
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.
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-INDJun 2024
Get to the airport with plenty of time before your flight. Sea-Tac is one busy airport!
Verified travelerFlew with Qatar AirwaysSEA-DOHJun 2024
Bring a seat cushion to add to your comfort
Verified travelerFlew with Alaska AirlinesSEA-BWIJul 2024
bring wireless earphones and chargers. you have to use your own phone if you want to watch movies or tv onboard.
FrankFlew with Alaska AirlinesSEA-TPAAug 2024
Make sure you have seat assigned at check in or you will have to wonder and be on a wait list.
kabirFlew with American AirlinesSEA-DFWAug 2024
Red eye flights can be a full flight. If possible, upgrade your seat. Stay away from sitting by flight attendant
Verified travelerFlew with Alaska AirlinesSEA-SJCAug 2024
The airport is busy and a mess with construction. There is a train to take so account for extra time.
Verified travelerFlew with Alaska AirlinesSEA-DFWJun 2024
If you like your feet warm, avoid wearing sandles. Cool air blew across my feet for almost four (4) hours.
Verified travelerFlew with Alaska AirlinesSEA-EATJul 2024
They will not wait for anyone so make sure you are there with plenty of time to spare
Verified travelerFlew with United AirlinesSEA-ORDJul 2024
Budget if you’re planning on shopping for meals or souvenirs at Sea-Tac, it’s not cheap.
Verified travelerFlew with Alaska AirlinesSEA-PHXJul 2024
Seattle is a busy gate. Find your gate first as connections may involve underground tram.
Verified travelerFlew with Alaska AirlinesSEA-DFWJul 2024
Arrive early. Busy airport and rental car return is far from Airport
Verified travelerFlew with Alaska AirlinesSEA-PITJun 2024
The SeaTac airport is huge and busy, get there early.
Verified travelerFlew with Alaska AirlinesSEA-DFWJun 2024
Bring snacks, water, and a change of clothes.
Verified travelerFlew with Singapore AirlinesSEA-SINAug 2024
If you need special meals book them early
Verified travelerFlew with Alaska AirlinesSEA-SNAAug 2024
Flight was delayed 9-1/2 hours. Make sure you have somewhere to go in you have to check out of your hotel.
Verified travelerFlew with FrontierSEA-LASAug 2024
Get there very early. The Seattle airport is nuts! I got there three hours early and barely made my flight!
Verified travelerFlew with LufthansaSEA-FRAApr 2024
If you don't have checked luggage, no need to be in a rush to line up. There will be a spot for your little carry-on rollie bag, so relax until the line is down to board the plane.
lizFlew with Asiana AirlinesSEA-ICNMay 2024
Do try to snooze on long haul flights, bring a good book to read, choose an aisle seat.
Verified travelerFlew with Alaska AirlinesSEA-LASApr 2024
Always come early so you don’t experience waiting times
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.
BrentFlew with Alaska AirlinesSEA-BNAMay 2024
Seattle is a cluster, too. You have to enter at one end of the terminal to check bags, walk to the other end of the terminal for non-Pre-TSA security checks, then back again to the starting end fir the boarding gates.
Verified travelerFlew with Air CanadaSEA-YVRMay 2024
If you are a solo traveler with intentions to not check bags then bring a flexible bag or smaller suitcase in case they put you on the small and dirty planes for your short connections.
PeggyFlew with Alaska AirlinesSEA-EWRMay 2024
Bring earbuds or head phones to watch movies on your electronic devices. The plane doesn’t have a screen for showing movies.
Verified travelerFlew with Alaska AirlinesSEA-SJDApr 2024
We arrived at the suggested 3 hours but sat for a long time. Maybe shorten your arrival to 2.5 hours
JayFlew with Alaska AirlinesSEA-JFKMay 2024

KirbyFlew with WestJetSEA-YYCApr 2024

Verified travelerFlew with British AirwaysSEA-LHRApr 2024
Bring a sack lunch -- airport food was very expensive.
Verified travelerFlew with DeltaSEA-MCOMar 2024
1.5hr early arrival for redeye flight was enough.
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.
Verified travelerFlew with Alaska AirlinesSEA-TPAFeb 2024
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…
LaurenFlew with DeltaSEA-LAXFeb 2024
If you have kids, bring your own screens. We were counting on the inflight entertainment and it was a definite letdown. Also, TSA Pre-check is only available at station 2, but wait times are posted at each station so you can see if it’s worth the walk.
Verified travelerFlew with Alaska AirlinesSEA-RNOJan 2024
have devices fully charged- no charging ports and no outlets gate check your bags because the compartments are SOOOO tiny and there is room for maybe 60% of the passengers to place items in these compartments
Verified travelerFlew with Alaska AirlinesSEA-BOIFeb 2024
Keep an eye on boarding time. At SEATAC, if you are not sitting at your exact gate, you cannot hear boarding announcements.
Verified travelerFlew with Air CanadaSEA-YVRJan 2024
Be prepared to have carry on luggage checked as overhead bins are very small and plane we flew on was old
Verified travelerFlew with Alaska AirlinesSEA-STLFeb 2024
Be sure to measure your wheels for carry on my luggage was the correct size but the wheels made it over so had to check my bag wasn't happy about that since you have to pay for checked should at least get one free.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Was delayed in Newark 24 hours due to mechanical problems. The staff was very helpful in trying to make the best of a trying situation. In SeaTac, they changed gates and times. Usually have no problems from SeaTac.

Flight was cancelled, then rebooked on a flight that I was unable to get through since they had closed the gate.

Terrible. We were bumped off our flight to another and weren't sent notice until we were on our prior flight. We got home four hours later and the airline couldn't have cared less.

Continuously changing delayed departure time. Too much waiting for a short flight. Driving would have been faster.

5 hours delay, while seated moved passengers around on the plane. We were out on the runway, had to return to the gate. Changed tires.

The flight was great, unfortunately the Airport sucked at accommodating connection flight. My Mother had to sleep at the airport, making me feel helpless. Unable to determine if I should sleep or drive 3 hours each way to pick her up.

Despite the delays with boarding and flying out of Seattle, the flight crew was amazing!! This was my second experience flying with Alaska, and given the chance in the future, I would fly with them again.

Terrible. After boarding we sat on the runway for 1.5 hours "25th in line to take off" ... Alaska Air is on 7th terminal , far away from rest of airport

Better sinage at check-in counter on lines for baggage check in and boarding pass check in, specfically at JFK. It was a mess to figure and wasted a lot of people's time.

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

On time flight. Seat comfort could be better in the Comfort section.

My issue was with TSA agents for delta airlines. My luggage got flagged. The agent was going thru another persons first. He took 20 min to go thru hers. I asked them to bring mine closer so I could sit down . They said you can go sit it will be fine. I said I am supposed to keep my eyes on my bags at all times. The agent was meticulously unwrapping 2 gifts that the lady had and then tried to re warp it. He was trying to be kind i get it but 20 min for me to stand watching him do that was ridiculous. It was 6 am and there were a ton of travelers. Mine was flagged for some air packed tea that I bought in Turkey. My previous delta flight and 2 others before didn’t flag it. Consistency would be nice. Also on the flight the window shades were down for take off and landing - I thought that was very odd I thought they had to remain open for take off and landing.

The flight was an hour and a half late departing which was inconvenient

Delay in SLC jammed us up in Chicago. Got caught up in rush hour traffic

The crew took good care of us. The flight from ATL to SFO is a longer one, and there were multiple beverage offerings. I like the 757's that Delta uses. Good airplane that is comfortable. I do wish Delta would separate Priority boarding from the better seats. I would gladly take a smaller seat in an open row than be jammed into Comfort just to get priority boarding, just to make sure I don't have to check a bag.

The flight was great. The gate location was way to far away!!!

My husband and I recently had an unfortunate experience with Lufthansa. At the Philadelphia International airport, the ground staff refused to board us because we didn’t have a current visa stamped on our passports for Frankfurt. We completely understand that this was our mistake. we should have double-checked the visa requirements before our trip. However, the issue that upset us most was how the situation was handled by the staff. They told us they would mark it as “boarding denied due to visa issue”, but instead they recorded it as “no show”. Because of that incorrect entry, our return flight was automatically cancelled as well, which caused additional stress and expense. Mistakes can happen, but we expected more transparency and accuracy from a reputed airline like Lufthansa. It would have made a big difference if the staff had been more careful and considerate in documenting the situation correctly.

Flight was good but there are way to many announcements for credit cards etc.

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

Boarding was organized. Old plane. Seat fairly comfortable. Business Class much too large so you don’t receive as much attention as you should considering what you pay for the seat.

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

Flight attendants on this flight were very attentive and friendly

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

Inbound plane was on time and flight departed on time with no issues while boarding.

I knew going into this that Frontier, being a low cost carrier, would be pretty bare bones and charge for most extras but this was made up for by the fact that the airplane was a reasonably new Airbus, every employee was great and best of all, Everett Washington is an amazing airport - thanks Frontier for flying there!!!

i was unable to check in the flight. refund requested

It was well done. It was my first time flying with them and I was nervous b/c I have heard of many cancelled and/or delray flights. Everything went smoothly.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company

Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

Frontier is the Walmart of airlines. Frontier has removed adjustability and comfort from their seats to make the flight lighter and save gas. This makes it impossible to sleep on their flights. Their customer service is abysmal. Once, I bought a drink on the plane, and they swiped my credit card on the plane to pay for it. Then I got three weeks of daily notices from my bank telling me they tried to charge the wrong card number over and over again. I tried to call them, but they removed the ability to actually talk to someone that can resolve such a problem from their company to cut corners. The only way to talk to someone in person is to go to the check-in counter at the airport (40 minutes drive from my house). Eventually their system gave up on trying to charge the card, after 21 days of repeated tries. They don't pad their prices even a little to handle customer service issues like missed flights. They also have a blanket policy preventing helping you reschedule a missed flight if their system says you "cancelled" your own flight online. This is a major problem because their website is broken on mobile devices, the only web browser you have at the airport when their gate staff tell you that you have to reschedule your own missed flight online because they can't help you. I tried to reschedule my flight on my android device and instead, their website crashed and "cancelled" my missed flight. When I got to the counter, the agent argued with me for 5 minutes insisting that I intentionally cancelled my own flight (implying I had to buy another flight). She missed the point: the problem was that I could not buy another flight because their website is broken. I left to avoid more conflict with the "customer service" agent. I tried to redress my issue with their only other "customer service" chanel available: the contact form on their website. The response I got was more of the same: you cancelled your own flight, according to our website / computer records, therefore we won't help you. I was trying to explain the problem with their broken website that cost me hundreds of dollars by crashing / malfunctioning and resulting in a cancelled flight, but they only had deaf ears for this problem. Worst customer service I have ever experienced. I will never buy another Frontier flight again, because it is a risky, painful move that I will likely regret often.
