A gluten free option I could actually eat would have been nice.

A gentleman at the desk for my boarding from Seattle to Anchorage randomly selected me and told me they would need to check my carry-on despite having multiple lithium-ion batteries all of which were in communication devices essential for time in Alaska. There was ample overhead compartment space and I was lucky non of my equipment was damaged due to his unnecessary use of power. A quick check with the flight crew would have likely resulted in an answer that ample space remained allowing me to keep my personal and important items near by. I did lose WiFi twice and that detracted from my entertainment which I do not commonly use.

The flight was fine. The connecting flight was a nightmare. Gate change without text or email notification was super frustrating and I ended up missing my connecting flight. Return flight was delayed and had I not quadruple checked flight time, gate and refreshed the Alaska Airlines app every 5 minutes, I would have taken a flight that would not arrive in time for my connecting flight. Ended up flying Delta home.

Hate this airline. Uncomfortable seats, no screens, no good food.

perfect flight!! couldn't have been better unless it was free!

Excellent overall, but had to wait 30 months while taxiing. In fact, I’m still on the plane now!

I liked the legroom even in row 26! I fell asleep immediately and slept the whole flight.

The plane was in pretty rough shape-- worn down with a bit of a smell. The crew as less than stellar as well.

Tight legroom. The breakfast was provided, which was a plus, and okay the taste.

my first time with Alaska Airlines, an exceptional airline with great employees.

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

Much better than the.last. flight on SW on Thanksgiving day

For the first time in a long time we had a flawless experience with Southwest. Both flights were early and no mechanical errors at all. We were shocked and pleasantly surprised 😮.

I stopped flying southwest a long time ago. I don’t care for their boarding process, especially when I have a family to try and seat together. The early bird check in made it so much easier. As long as you do that, it’s great.

Everything was very good. I will fly Southwest again soon!

Nice and easy. You can't go wrong with the value and quality or Southwest.

Flight was cancelled due to “inclement weather” even though all other carriers continued to operate as planned.

sw cancelled our flight 2 hours before we were to leave. Our bags were already checked. Only communication we had was a text that had a link to reschedule that did not work. When we finally got to front of line ticket agent said they could not get us on a flight until Wednesday. This was Sunday. 3 days. The. They stated since it was “weather” related they would not give us vouchers for food, hotel stay anything. So we had to book on a different airline costing us an extra $1000. Unacceptable.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Flight was warm for first few hours and quite rough

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

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

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

Older aircraft, no meal, only food was for purchase. Not impressed United.

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

Late boarding by three hours. No Wi-Fi. No screens. Cramped seats. Sitting on the tarmac for 30 minutes after landing waiting for a gate. Delay in luggage getting to baggage claim.

Flight pulled out on time but sat on runway for 30 mins. It was extremely cold in the aircraft despite wearing a winter coat. Surprisingly they had a vegetarian meal but could have some better snack choices for a 8 hour flight.

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

It went up and down at the right time and place. I’m happy with that outcome.

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

It was a good flight - not overbooked and in time.

It was perfect in almost all ways. In fact it arrived early in both legs of my flight. The entertainment was marginal, but that was due mostly to the length of the flight. I love American!

Thankfully no connections off of this one on the day of the flight as it was delayed 90+ minutes.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

Flight was delayed an hour. The pilot said we could deplane but that we wouldn’t be able to get back on. Luckily, my layover in ORD was 2 hours and it didn’t affect my connection. But a lot of people missed their connection and a handful of people elected to get off the plane. There were a lot of upset people and the American crew didn’t seem very sympathetic or accommodating.
