The one stewardess was rude about helping me put my bag in overhead….she said “ Is it heavy ?” (I am 73 yrs old)

That flight was a terrible experience. Flying to Portland was not much better. I will not ever fly Alaska Airlines again. I have a temporary disability due to recent neurocervical surgery. I cannot lift heavy things, I cannot walk long distances without vertigo and fainting, and I required wheelchair assistance. I showed up an hour and a half before my flight. The wheelchair queue assistance person was rude and chastised me for showing up so late. An older couple showed up almost an half an hour AFTER me, and she was sweet as pie to them. There was a long wait for wheelchair assistance as they were backed up. When I got to the gate, the gate attendants were rude and again, I got chastised for being late, even though it was not my fault they were backed up. When I asked for help with my bags and boarding the plane, they told me it was my fault and they were not obligated to help me. I was treated like a big inconvenience because I had a wheelchair and I couldn't "just walk." One of them literally rolled her eyes at me. I kept silent, because I just wanted to get home and I felt like they would not let me on if I complained, but I was practically crying. When I got down to the door to board, the wheelchair person left, and I asked the flight attendants for help. They said, well, you'll have to stand there and wait, even though I said I couldn't stand very long, and another passenger said, "Oh just let me do it" and helped me down. I tried not to bother the inflight attendants, because everytime you did, they acted exasperated and stressed out. I paid $7.50 for a bag of Pirate Booty and a tiny turkey beef stick for dinner. I needed wifi to work during the flight, and it kept crashing on me repeatedly and resetting my online work, costing me valuable time. I had to pay twice to get it on my laptop and phone, but I did get a refund when I returned. When I got to NY, the Portland agents had not arranged for a wheelchair to meet me and I had to stand for fifteen minutes waiting for the very nice young man who found an empty chair and had to wheel me and another passenger with carry on luggage to the front of JFK all by himself. Never, ever again. You all should be ashamed of how you treat people with disabilities. The other people who needed assistance to get on this flight did not fare much better than me, from what I could see.

My experience for a sort flight was perfect and hassle free.

I didn’t like not knowing my seat till I got to the airport - and my boarding group was F (last).

My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

Horrible. I likely will have to spend several thousand dollars to rebook my international flights, due to their delays, plus a hotel in SF. I can’t wait to never fly them again!

Quick easy boarding. Airport was unprepared for early landing and we were waiting in the plane for 20 minutes before getting a gate.

It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

Staff seemed genuinely nice, not just going through the motions.

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.
