Everything was great but there were no entertainment options available.

Everything was great but there were no entertainment options available.

No prob with entertainment-would have selected n/a if it had been an option. No entertainment-flight was only a short hop. Great flight,

Loved the airport. The announcements for boarding were too loud & echoing in the large waiting area, so hard to follow. Other than that, we had a great experience.

Staff was very friendly. Flight was on time and arrived early. Flight was comfortable.

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.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

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!
