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 
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.

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.

Seattle airport is a nightmare. Too much construction leading to confusion where to go and poor signage. Really crowded airport and waiting areas.

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.

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.

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.

There was a engine problem, so we had to deboard and wait on a new plane but that just happens sometimes, and crew was very efficient and nice.

Cathay Pacific is an excellent, well-maintained airline. While I too would love to fly first, or business class, I did not. I actually had the dreaded middle seat in the middle row, and yet, since I am an inquisitive traveler, I introduced myself to my row mates and had nice chats with both until lights out. Pro tip: Bring a donut travel pillow no matter where your seat is! The flight was smooth, the restrooms clean and the staff courteous and efficient. I gave the comfort level a 4 because of the reasons listed above. The airline meals... let's face it ... it's airplane food but CP does a good job in making it as edible as possible.

I was not able to figure out how to get the entertainment. But the flight was smooth and quick.

you have to buy the wifi for entertainment. flight was packed but crew was nice.

Again, the Alaska boarding area at Sea-Tac is gross.

It was fine but the Seattle airport was terrible. It took over 2 hours to get from rental car return to gate! There was no one to help with check in and bag drop. It is not a people friendly airport…too long to walk, too many levels, no help. If it is possible to pass this on, please do. It seems it is Alaska’s main airport.

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,

Lots of turbulence in last 45 minutes, but captain kept us very well informed, which was a big help to a nervous flyer.

Boarding took longer, to shuttle to plane. Crew/pilot were great.

Meh. It was the cheapest option, but not cheap for a mid-week flight. The flight staff were the most brisk and passive-aggressive I've seen on a flight in forever. We got to the destination alive though.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Flight did not have seat back entertainment and the wifi was iffy.

Pretty standard flight. Delta has a good selection of movies.

The WiFi has been awful on my last few Delta Air Lines flights.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats are uncomfortable and there was no power to recharge a phone.

Flight heavily delayed. No food available despite purchasing an upgrade. No in cabin service.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The free internet access did not work, so we had to purchase 2 Internet packages. Flight attendants were not proactive in checking in with first class patrons

The flight attendants were talking the entire time on the back and I couldn’t even take a nap. Super annoying

11h50m total delay. Had to switch to another flight that was still a 7h30m delay.

A very good flight. All personnel were gracious and pleasant. Good flight. No complaints.

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

The crew was ghetto lol I felt like I was on an inner city field trip

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

There was nothing to like, flight delayed had to move to different departure areas, disorganized to say the leasr

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.
