I had to cancel my trip due to health reasons three days after making the reservation. I was stunned to find out that the ticket was not able to be credited for future travel. $734 loss. Not happy that this was not my experience with Southwest Airlines. I will stick with SW in the future. Boo Alaskan Air and Kayak.

Due to plane delays on both legs of my flight home, I had to be rerouted from Santa Rosa to Las Vegas on Skywest and then to DCA on American. SkyWest airlines sat on runway in Las Vegas for 20 minutes waiting for gate to clear. My boarding pass for American that I was given by Alaska was incomplete and the Las Vegas airport lacked signage and departure boards. I barely made my flight bc it was so confusing. American Airlines has a much better wireless connection. I’ll never fly Alaska again. It clearly has problems.

Great. I did have a little issue getting into the Lounge, which is likely more an American Airlines issue. I did not carry my physical AAdvantage Executive credit card with me on this trip, which Admirals Club membership is a part of the benefits of having this card. The instructions on the AA website and the Citi cards website make it seem like you don't need the physical card, as both sites state you can enter with your boarding pass and driver's license. But both lounges said you were required to present the physical card (and not the digital version, via Apple Pay), as only the physical card says "Admirals Club" on the back.I also do not have a physical Admirals Club membership card, so while both lounges eventually let me in, both denied me entrance initially for this reason.

I paid for wifi and it never worked... it was miserable. I couldn't access my shared files to work on the plane, it didn't work on my phone. I paid for nothing but frustration and continual refreshing, hoping it would work

We left about 30 minutes late due to ramp issues. It did not impact me, but I know others on the flight had very tight connections to Maui.

The stewardess are very nice and pleasant, Someone onboard had a medical attention, and they attended that person non-stop all throughout the flight, and yet, did not forget to serve and help other passengers.

Everything from the time I booked my flight through to the end when I got home was smooth and wonderful. Service was great, the flight attendants were attentive and there were no outstanding delays.

The staff was extremely helpful and accommodating. The only thing I could have done without was the long layover in between flights but I was going to a less popular destination so it was understandable.

Flight attendants made this flight wonderful. They made sure everyone had what they needed and anticipated future needs. They made adjustments as needed. It was clear this was an experienced crew.

Worst first/business class I have ever flown after 75 years on planes. Barely acceptable seats, terrible food, uninterested attendants, unavailable WiFi. I’ll never fly this airline again.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

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

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The seats were comfortable, and the boarding process was pretty smooth.

3 hour delay. Had to change plans and was still delayed.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Timing, quality of service, promptness and courtesy of the staff

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.

My flight out of Baton Rouge to Atlanta was delayed by a half hour. This got us into Atlanta airport 30 minutes late. I ran through the airport to get to my connecting flight. As I approached the boarding gate, I saw the boarding door was still open and a passenger was being checked in. But when I got to the gate, the boarding agent told me they had already given away my seat and there were no empty seats on that flight. So I had to take a later flight. That has never happened to me before. Very frustrating.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

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

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

The gate attendant let me walk right by her with a bag too big for the overhead compartment
