Easy and quick boarding. A bit of a hard landing at PDX

I think u could offer more than apple juice or water.

Pleasant crew and on time travel. It was all good.

It was ok. Alaska was adequate. Efficient and what I paid for it was fair. The boarding area at the gate was a joke. By the time they get past the C boarding group people all line up impatiently and then it’s chaos. We were boarding early then we sat on the tarmac for 30 minutes. I would of rather sat in the airport.

The entire flight was terrible. I recently had neurocervical surgery, and I needed a wheelchair to get to the gate. They were wonderful, truly. The flight staff was lovely, as well. Despite the need for assistance, I was put in the middle seat in the last row in front of the toilets. It was "policy" that I couldn't be moved. The pain I felt after the flight was astromnomical. The flight was so WARM, I was sweating, and the "air" did nothing to the stuffy feeling. The seats were uncomfortable, the plane itself was in bad/worn condition (although very clean - thanks to the staff) - and the flight was definitely rocky (not the pilot's fault, of course). All in all - one of the worst flights I've ever taken. The humans were wonderful!! You have a really great team. But your flight policies and your plane are absymal. For what you charge, you need to upgrade your plane and your policies.

First flights on Alaska Air, and I will go out of my way to fly them whenever I can in the future. An incredible experience, above and beyond any other airline.

The seats were incredibly small and the attendants were grumpy the whole time.

It was a tiny plane … even though I paid for upgrade, no internet… no plug ins, no entertainment… 👎🏻

Alaska continues to provide one of the best domestic US airline experiences.

I liked the fast internet and twice serving of snacks and drinks. Paid food options could have included more.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

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

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

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

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

Flight was good, boarding was a breeze, flight attendants were friendly and professional. There was a medical issue with another passenger and the crew handled it in a calm and professional way.

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.
