It was fine. It was a 30 minute flight so there was water or fruit juice and no food. Which was totally fine. The check in, gate and flight crew were all excellent.

I didn’t order food so can’t really say how it was. Overall, it was a great experience.

Had to sit and wait to get off the plane for closeto a hour. My son also flying to a different destination that day also had like a 2.5 hr delay

Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

Flight was delayed which led to missed connection, but rebooked on a more direct flight at the last minute and arrived in Juneau on time with all our luggage. Little stressful and our family seating got split, but it all worked out in the end.

they didn't fix a plane and we were delayed travelling an extra 12 hours.

This flight was how a flight should be. The flight from Hawaii to Seattle was terrible

While the flight itself was pleasant, the process of checking in was difficult. The line was long and our connection time was but two hours. When we finally got to the Hawaiian agent and told him that we were traveling on Alaskan Airlines, he told us we would need to go to a different terminal. I told him that another Hawaiian Airlines agent had directed us to him. I’m looking at our tickets, he noticed that the Alaskan Airlines flight was to be managed by a second party. He ended admonish us for not telling us so Rather than considering that we might’ve been right in the first place.

Plane left an hour late due to flight staffing problems. Only a 45 min flight, but it took 3 hours as a result, which left a lot of people disgruntled. No excuses. No recompense.

The staff are friendly and happy, the check in online was easy and dropping off the bags went well with out problem.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was great. The gate staff were very helpful in Portland when my son forgot his rolling bag and had to go back to get it just in time to make it on the plane. We really appreciate that. Great job!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

Everything went smoothly and we even arrived a little bit early.

Connecting flight is on time and boarding was a breeze!

WiFi did not work. For as outrageous as these flights cost, when they’re advertised with certain services/ features they should be in working order

I would have liked to arrive on time - not 5 hours late!

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.

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

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

worst flight ever from Delta, it got delayed and kept on delaying..

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

This flight was supposed to land at 10:55 pm on January 14th. Instead, it landed at 3:20 am on Monday, January 15th, resulting in a completely lost day due to not going to bed until 5:00 am.

We finally got on a flight about 10:45 that was to leave at 7:30. Bah humbug!

Very easy ! Use the kiosk and bag drop and right to security within 10 min

This planes staff was top tier. Everything went great and had a great flight home.

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

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.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Had a hard time finding my assigned seat. No attendants to assist.

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

Everything was great, only problem was that flights were delayed

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.

Any sort of gluten free snack option would be nice

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

It would have been better if I could have had my flight on time. It was delayed for 5 hours. Caused me to not be able to fulfill my promise to my granddaughters. Other than that it was a good trip.

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

Delay 14 hours! Missed all connections and had to fly different airline the next day.
