On time departure & early arrival made the long day much better

It was insanely hot on the flight - especially before takeoff and then when we landed - but I was literally sweating in flight.

Alaska changed their departure time 4 (!!!) times, then couldn't find my luggage from a direct flight from Spokane to Portland. There were 11 passengers who didn't get our luggage & had to wait 40 minutes for Alaska to find our luggage. Alaska should reimburse everyone their airfare for such inexcusable service.

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.

It was a very smooth fast flight, crew was prompt and comforting. Alaska airlines are the best.

It was a really smooth flight. I hate heights. All made it feel smooth. Thankyou

Somehow I didn't get the chance to pick my seat and got stuck with a window seat. After I checked in, I could get an aisle seat but had to upgrade, which made little sense on an hour long flight.

We had no food or enjoyed entertainment. Flight was only about 1 hour. Lovely experience.

I couldn't cancel or change my flight so I paid for nothing.

Flight was excellent. Food and entertainment did not apply that is the reason for 3.

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

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

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

On time departure and early arrival. Kind and professional service from flight crew

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

I had to cancel the flight because with a 3 hour delay for 'unexpected maintenance' in getting to LAX, I couldn't connect to an overseas flight that I had booked on Scandinavian Air.

My flight was delayed three hours and then cancelled. The gate agent proceeded to rebook me in a middle seat without telling me and I was placed between two large individuals who did not fit in their own seats and instead took up most of mine. It was an awful experience.

Good and friendly staff. Nicely enjoyed the complimentary drink and snack.

Would have been better if the flight went out as scheduled and we’d have been kept informed. Rescheduling the connecting flight out of Portland was especially difficult.

All was good and they were able to seat my travel companion next to me. Thank you.

It was a great flight and nice experience. Would fly Alaska airlines again!

Alaska airlines is not what I expected Very disappointed Unfriendly Discouraging Very bad customer service, heartbroken trying to explain to them my situation.

Flight information board was not immediately available; however, it was not far from where I disembarked to my next flight.

Terrible. A four hour delay to take off is unacceptable. arriving in Portland at 1:00 A.M.

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

A very pleasant flight but it would be greatly improved with wifi to help entertain kids

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

Seats were very uncomfortable and being charged for snacks and water.........

Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.

Good, but a bit late on take off after loading. Don't like charging for carry ons!
