It sucks, flight delays at FAT caused us to miss a day at lodge and overnight in Seattle. Flight delays coming home also. Never again

It sucks, flight delays at FAT caused us to miss a day at lodge and overnight in Seattle. Flight delays coming home also. Never again

The plane was late taking off. We sat on the plane at least 45-60 minutes before moving away from the gate. Im 5’9” and 185lbs and there is no room in those seats. On top of that you shoehorn a waterbuffalo of a woman in the middle seat to where her sweaty rolls and arms were well into my seat and touching me the whole time. It was either that or press against the opposite arm rest and get hit by the beverage cart and every single person who walked by.

I am mobility challenged and ground crew were accommodating to my needs. One must walk up a ramp to board Alaska planes. Terminal to tarmac to ramp to plane.

PAID First class. No use of lounge in Phoenix (should have a code share). Bags checked and not marked first class, asked attendant who stated on mark gold members. Last bag out of carousel. When you pay extra, expect that...wifi was rebooted and not functioning to allow internet access. Food and cree were very good.

Very Large person sitting next to me and taking up a lot of space including mine

There was no sense of urgency to get us to our destination on time. There’s just no such thing with this airline. It’s not my fault, they don’t have enough help. They sure as hell charge you enough for everything Nothing like being nickel and dimed to death. Money for bags money to choose a seat. You gotta be made for money to fly this airline.

Three hour flight so snacks and basic drinks unless you pre buy as usual. Didn’t do my emtertainment as was tired after 23 hours of travel. You have to use your own device on US flights if travelers aren’t aware so if you only use your cell phone that can be small. Crew are great.

It was very good. I love flying with Alaska air.

Everything smooth (including the landing) and on time. Easy. Thanks.

My flight was canceled and rebooked about 3 times. Original flight had a 50 minute layover. Flight was canceled and rebooked with a five plus hour layover. I demanded refund

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.

I am still upset that my bag was lost on a recent trip to Rome ; we were inconvenienced and out €150 Euros ; delta has refused to reimburse us

I am very bothered by the events today. I can't believe the flight attendants allowed someone to take my seat and made me move. It was embarrassing. I was in the right. The lady just didn't want move. I can't believe delta would allow this to stand and disrespect my rights as a passenger. The lady complained about her leg and that she couldn't move. Firstly somehow she was able to make it to row 24. Not sure how much her leg could have hurt. Secondly, I'm in plenty of pain myself. I just finished chemotherapy a several weeks ago. My body is constantly sore. Yet deltas flight attendants didn't appropriately protect my rights. In the end they found me a seat on the plane but I want to understand how delta can operate this way. They in essence allowed a bully to get their way.
