I got to my destination but no comforts no snacks nothing. Like herding cows!!

My only comment was the confusion at Houston. Suppose to leave at 6 am and didn't leave til 11 am. Then moving from gate 10 to 30 and couple of hours later back to gate 10. Otherwise everyone everything was great.

The food options could be better. Possibly some sandwiches to be added to the menu.

There was a medical emergency on board the crew handled it very professionally and the ambulance crew as well. I am very impressed. Thank you Clyde Barron 31 D

Checking in was very easy. Boarding and the flights went smoothly.

I have never flown Alaska Airlines before & would recommend them to anyone& will use again

Not a good experience, we were delayed by an hour due to maintenance issues.

After upgrading and paying for seat I was bumped from my seat. When I went to ask why she said I wasn’t assigned a seat because the ticket I purchased. After kindly explaining to her I upgraded the night before and paid for that seat she said how I was wrong and that something must have happened. I showed her my receipt and she still said there was an error. This is why I only fly delta. The flight attendant was rude as well but I don’t want to waste anymore time talking about how poor Alaska is. Delta here I come!

Ashley - the flight attendant from OMA to SEA - was phenomenal. I was traveling alone with my 4 month old and she made every accommodation possible and went out of her way to make sure my experience was as comfortable as possible. Give this woman a massive raise!

boarding was easy and the 737 Max was comfortable and roomy but that was the only good.. there was a child screaming at the top of his lungs for the entire loading, taxiing and part of the flight and no one in the crew said anything or offered any assistance.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

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...

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

Delayed so that missed connecting flight. Connecting flight was also delayed on the tarmac but they closed the gate before the rescheduled time.

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Took off over an hour late with multiple mechanical issues. Gate agent in Dallas was lazy and was slow as molasses. Had a line 10 people long. Spirit bad..

The flight was short. However, my bag was delayed and was put on another flight.

Flight attendant was incredible. Very efficient, friendly and pleasant. Patricia was one of the best I have ever seen. Please give her a big raise!

LIT to DFW - 3 hours late; the entire plane had been boarded before they told us there was a delay due to a weather-related ground stop in Dallas. DFW to MAY - 2+ hours late due to A/C needing to be repaired after everyone had boarded, then when we finally reach the runway, the First Officer timed out and we had to taxi all the way back to the gate and wait for a new one. I arrived in New Orleans 5+ hours later than I should have. Return flights were completely cancelled; rebooked through the app to fly through CLT instead of DFW. MSY to CLT had no issues, but CLT to LIT was delayed 1.25 hrs because flight attendants had not arrived to the airport yet. At least they didn’t make us all sit on the plane to wait for them. I should have driven.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in-flight WiFi. Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay that much for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a shitty attitude for no reason, nor will they act the way this woman did. Unacceptable.

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I got a one-way, last-minute nonstop flight from PDX to BWI for only $125. Yes, I got nicked $79 more for a checked suitcase and $89 more for the BIG SEAT option, but it was worth it, even with $4.50 for coffee and $10 for a snack (the latter no different than any other airline). The grand total was still less flying on any other airline.

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

This recognisable no-frills airline gets me from point-A to point-B. I was able to get to Chicago without stress. The checked baggage collection and reclaim could be improved.

The crew was the best and very accommodating I know you don't offer any complimentary items but water and coffee will not break the bank !!

My flight was cancelled!!! I had to spend 200.00 on another flight!!

The whole day was a nightmare. Flight extremely late. Boarding was a mess of a nightmare.

When we landed, they kept us on the plane for almost 25 minutes. Could do better.

worst trip ever Spirit lost our Baggs which were never put on the plane in Atlanta. 24 hours ago they are telling me now that the bags are still missing.

Never been on this flight as i had missed it due to delayed connecting flight

Horrible. Delays, no customer support and fake promises and everything. i am suffering to help as due to connecting flight getting missed no support on ground and customer support window is closed and we are sitting o ground without anything
