I always choose Alaska when I can. Every thing seems to run more efficiently with them.

I got my seat changed last minute so a parent coumd sit with their child wich i found out was a teenager

I liked that I made it onto the flight rather than “missing” the connection. We left PDX early in the morning along with half of Portland arriving at about the same time as we did- 2 hours prior to our flight leaving. The layover was for less than an hour and we were concerned that we would not make the connection, but as it turns out, the flight leaving LAX was even more delayed in departure due to needing some maintenance repair for the a/c of the plane. As for the food- it seems not so very nice that you are not feeding people and offering complementary alcohol on the international flights any more.

Flight was delayed but still made it to Phoenix on time. Boarding went quickly, the flight was smooth.

The food selections were not good, and entertainment was non existent.

Fine. But given how empty the flight was, I do not understand why my dog, in its carrier, could not be placed on the seat next to me (which was empty) rather than on the floor under seat. This seemed like overkill on the rule following by the flight staff.

A very good experience - all staff was friendly and helpful.

I would have liked if the flight existed. To be fair the federal government canceled it. But, since it WAS canceled, I would have liked it if Alaska Airlines had moved a finger to assist me rather then abandoning me with my luggage, unable to check it, for 14 hours in Portland. So federal regulations forbid them from storing my bag? Then at least help me find storage or SOMETHING.

It was all good, no delays which was a worry. All great

The staff was so kind and friendly! Boarding was efficient and communication was timely. I would seek out flying with Alaska Airlines in the future.

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Great. I had to modify a flight. That was easy and free. Thank You

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

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

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

Very crowded flight but what can you expect these days?? Crew was accommodating.

The seats in economy were appeared to be quite thin and lack sufficient cushioning to be comfortable. Perhaps it was my seating position but the plane seemed notably load.

Internet was a bit expensive and did not work ask that week otherwise a good flight

The flight had a delay that made me being in a real rush to take the second flight. The delay was almost for 2 hours. They moved us from gate to gate in 4 times. Once I arrived to Philadelphia, I got to run thorough all the airport, as the train was already closed by that time. So I got sick with asthma for all the running I had to do. And I was the last one to board, when it was almost closed. So irresponsable with the people

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

Everything was great except British airways lost our luggage that was gate checked all the way through to Italy. No one knows currently where one is and the other one may be in route to Amsterdam to meet us but not sure. If you can Hale’s it would be awesome. The website is not helpful.
