Verified travelerFlew with Alaska Airlines-Feb 2026
Purchase one of those luggage covers because your bag might end up being checked regardless. Download episodes before your flight because they don’t always offer in-flight wifi.
Verified travelerFlew with Alaska Airlines-Feb 2026
Make sure you have a REAL ID and not just a drivers license. It’s a $45 fee to get it processed the TSA rep told me.
LaveniaFlew with Alaska Airlines-Dec 2025
Pre-order your food. Make sure to bring your OWN device and be prepared to pay for WiFi to access entertainment for this long flight.
Verified travelerFlew with Alaska Airlines-Feb 2026
The seats are narrow. If you are large and expect to take up more space than your own seat, book two seats.
Verified travelerFlew with Alaska Airlines-Jan 2026
Never choose Seattle as a layover city. The airport routinely doesn’t have gates ready for incoming planes.
ManojFlew with Alaska Airlines-Nov 2025
Don’t bring carry on roller luggage if you can avoid it. Overhead space runs out real quick.
Verified travelerFlew with Alaska Airlines-Apr 2025
I like Alaska. If you need a screen attached in front of your seat, better to check your flights first.
KaylaFlew with Alaska Airlines-Apr 2025
Be prepared for possible long wait at security, make sure to check baggage policies and carry one allowances.
MargaretFlew with Hawaiian Airlines-May 2025
The delays we experienced on both flights to and from were cancelled or delayed which made for a very stressful trip. I would suggest monitoring the flight status continuously before arriving at the airport.
TonyFlew with Alaska Airlines-Dec 2024
Pack snacks or a good sandwich. Download your movies before you fly to avoid another FINE/FEE for internet charges. Pack light to avoid luggage fines/fees for check in baggage Don't pick a seat to avoid fines/fees
Verified travelerFlew with Alaska Airlines-Jan 2025
Seattle airports have lots of stuff to look at and buy. However if you are a little person who is always cold, ware a long coat and layers to stay warm. Maybe even take gloves.
AlanFlew with Alaska Airlines-Dec 2024
We need more maps or layouts of the airport available and what's available when flying to the next airport or where terminals are located to maximize time when there are layovers.
Verified travelerFlew with Alaska Airlines-Sep 2024
Buy something in the airport to eat before boarding as its a long flight and the snacks are not enough unless you plan to sleep the whole ride.
Verified travelerFlew with Alaska Airlines-Nov 2024
Ck in and download your electronic tickets beforehand so you can use the baggage check in kiosk. Will save you a lot of time not standing in line.

PaulFlew with Alaska Airlines-Jun 2024
It's pricier to fly into Reagan (DCA), but if your destination is core DC area, it is well worth it. I used Ubers and Metro; no need to rent a car.
Verified travelerFlew with Alaska Airlines-Jul 2024
It is a very crowded flight, so I advice to choose seats in advance. We didn’t have that option and that was the only complaint I’d have because they put us in the middle seats and we both wanted aisle seats. My sister was able to switch but I wasn’t. She was switched to the back, almost to the last row.
Verified travelerFlew with Alaska Airlines-Jul 2024
Its a long flight so if you want snacks bring you own.
NolanFlew with Alaska Airlines-Jun 2024
Two-aisle configuration; Reasonable number of rest rooms; Bring your own food.

Be prepared for the disorientation of SeaTac as the entire terminal appears to be under construction. It’s unnerving.
NickFlew with Alaska Airlines-Jun 2024
Bring a bottle of water on board with you. It took three hours for us to be served.
Verified travelerFlew with Alaska Airlines-May 2024
Be sure to get instructions on how to get to your connecting gate as Seatac airport is pretty big and uses a subway like train to get from one terminal to the next.
Verified travelerFlew with Alaska Airlines-Mar 2024
Research the details of the flight. Particularly, cost ofluggage, safety record, and seating per square foot. If you arrive safely, your fortunate. It was an excellent flight.

Verified travelerFlew with Alaska Airlines-May 2024
Get to the airport early, especially on holidays
PaulFlew with Alaska Airlines-Apr 2024
The flight is long, at over four hours. I would try to get a window or aisle seat to be more comfortable. I would check with other airlines that allow you to choose your seat even if you are in the economy section. I would bring your own food on the plane as the service was sometimes sketchy.
Verified travelerFlew with American Airlines-Apr 2024
bring your own tablet or laptop if you want to watch movies on decent size screen... and consider continuing to mask while traveling to avoid variety of airborne diseases.

Bring or buy food before you board. Including drinks

Get a nonstop flight. The extra leg room is worth it for tall people. Did not get it for the return flight (already over budget), so we will see how that goes.

Employees are always helpful and professional. The flight was 30 minutes delayed but everything else went seemlessly.

Boarded us on a plane that had ongoing maintenance and it was 105 degrees out. Sat in the cooking heat for an hour before taking off. WiFi didn’t work over half the flight so I couldn’t get any work done

Awful. Flights were delayed due to FAA which is out of your control I understand, but the communication was awful. Kept getting further and further delayed and then a different flight that was supposed to take off after ours actually took off before us. One of the employees was super rude, too.

Customer service at Juneau was great but the handling of our luggage was very poor at Seattle after a delayed flight due to maintenance causing us to miss our connecting flight. We had frozen goods and they told us they would put it the freezer but didn’t. We lost 250lbs of halibut & salmon

late flight, no wifi, no entertainment, no snack. What are you coming to????

I lost a bag in the process of getting home and I’m a little stressed about it

The delays were the real problem. The crew and staff were amazing and kept us informed and taken care of but what should have been a 6 hour flight with 1.5 hour wait ended up being a 13 hour day in the airport and in the plane waiting to board then waiting for takeoff. Great flight once we got in the air. Pilots and flight crew were awesome 😎.

It was a 3 plus hour flight. By hour 2 my butt was really sore! Loved having wi-fi for the whole trip!

Flight boarded super late. Missed our departure window. Stuck on the runway for over an hour.

Crew were great. Complimentary food was very disappointing. On an early morning flight lasting over 2 hours, a tiny cookie and small drink is inadequate. How about a cinnamon roll or something else a little more substantial.

The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

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

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

The most cramped seating I’ve ever experienced, (including budget airlines) with no food available for purchase on a nearly 6 hour flight.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

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

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours

Very smooth for one of the busiest travel days of the year and the crew was great.

Customer service prior to boarding is horrible Communication regarding boarding gates is released at the last minute and the gates are very distant from Customs. Very disappointing

Remind customers of the need to have passport or new ID for boarding.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

Horrible. I would never fly Frontier again. The booking process is tricky at best, but fraudulent in my opinion. Frontier customer service did nothing to rectify my purchase -- I ended up paying more than double what I could have gotten from other airlines and nearly triple what I thought I was buying from Frontier. Their booking practices are unfair to the consumer.

I’m not gonna fly Frontier Airlines because booking is not an option. No water or food is for high price, not equipped for health emergency incompetent crew for emergency services. Cheap airline shows it is cheaper in all service categories. Boarding is the best of all airlines!

The seats were extremely hard and uncomfortable, even for a budget airline.

Boarding was very well executed. Got my bag right away.

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

I didn't get to do this flight l, hard to review

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

The whole experience was bad. Didn't know no complimentary drinks or snacks. $4.39 for a soda is ridiculous even a bottle water. A carry on was $74 just crazy. I don't think I will take this airline ever again. Very bad
