There was no food or entertainment, thus thus the neutral rating.

The Alaska Airlines app made it very difficult to find my boarding pass. It was very frustrating to use! The flight itself was flawless.

No communication with delayed and canceled flights. Completely in the dark for the whole experience.

You need categories to denote when food and entertainment are not available.

Alaska is generally the airline I fly nearly all the time. I nearly always have wonderful experiences on Alaska and never a complaint. However, this entire flight felt like we were in the cheap seats the entire time and I had even upgraded to a cushier seat. For an over six hour flight (that became 7 hours) there was no online entertainment. I couldn’t connect to Wi-Fi and we were offered one snack and one drink. We were instructed to go to a particular baggage claim and 30 minutes later our bag still hadn’t come out and it turned out it was the wrong carousel announced. So overall, this flight was a series of mishaps really less than mediocre service even though flight attendants were wonderful.

Alaska is a great airline. Unfortunately, our flight was canceled in a really late hour and it caused a lot of hardship in my travel process.

More comfortable than the flight to Los Angeles. But food was mediocre again. Attendants kind and courteous.

Alaska Airlines has the best service of airlines I have flown the last couple years. I always choose them first.

I haven’t flown in over 20 years and had my grandkids, so I had lots of questions. They were very polite and helpful . Thank you.

I know there were a lot of delayed flights, mine from Portland to Eugene was delayed by 3 hours, but not from one employee was there a" we are so sorry about the delay or is there anything we could get you, I thought it was very un-professional and rude.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

No in flight service, no explanation - FC got service, C+ did not, unsure about Economy. No turbulence to speak of, so I guess another way to cut cost, or promote health and well being of Delta employees? Also, boarding in MEM combined zones, and with overhead space already full on both flights after Zone 2/ Diamond, presents a huge challenge to find a space for a bag. Delta, other than point A to B, is no longer reasonable to fly - very poor experiences, not even taking into account the chastising at the gate and rude crews, across the board.

It would have been better if the flight wasn't delayed by 2.5 hours

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Delta flight Delay for ,more that two hours i.e original flight was 6.30 PM and it starts at 8.45 PM, When we connect Delta team for meal vouchers as it is late arrival in designation,But we did not get it as per delta policy , which is not good for mid night arrival,

Inexperienced boarding crew allowed too many bags on to a full flight and delayed takeoff causing a missed connection and unplanned overnight stay. There was a hotel at the airport but Delta would not pay for it offering only to shuttle me to an area hotel. Never even offerred so much as an apology by anyone working for Delta.

Staff was great! Kind and cordial! Middle seat row 28 seat B has a hump in it. Trays were getting stuck when putting down and up. Good flight

Departure was delayed resulting in me missing my connection. Delta did not autimatically find me another flight.

The seats weren’t reclining even though it wasn’t as exit seat

It was good because we traveled without luggage, carry on only.
