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.

I appreciated the ability to choose between multiple flights both into and out of Portland from Burbank on the same day, so we were able to attend an event and return without spending the night. I am unable to appreciate what Alaska Air calls "streamlining" the checkin/boarding process at Burbank Airport. If you have a smartphone and the Alaska Air app, it is probably fine, but removing the option of using onsite kiosks to print boarding passes does not meet my definition of "streamlined". I also found it challenging that both Portland and Burbank airports required the plane to sit on the runway for some time due to lack of an open gate at which to disembark. It would not be so bad if we could at least remove our seat belts and move a little bit while we waited, but that is not an option. I honestly don't know whether this is because of how Alaska Air operates, or just the circumstances of the particular day and airports we were using, but I normally do not experience these kinds of delays to reach a gate using Southwest Air.

I was not given a seat when I bought the ticket. I know airlines are trying to squeeze every penny out ot the customer, but we are buying a seat on the airplane, right? I find this irritating with all airlines, but especially Alaska because I fly it so often. No sense of customer use and loyalty.

It was adequate nothing special no entertain because flight was short. Crew pleasant.

All employees were very nice and I was very comfortable

Loved the gate agent and flight attendants. All were extremely helpful.

It was a good flight, wish they would have handed out snacks though.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.
