I wasn’t able to check in prior to arriving at the airport, I was told by the agent I may not get a seat on the plane as others were waiting for seats, I sat there for 2 hours before being assigned a seat, very stressful. The plane was delayed. Overall not a great travel experience for a 44 minute flight.

I wasn’t able to check in prior to arriving at the airport, I was told by the agent I may not get a seat on the plane as others were waiting for seats, I sat there for 2 hours before being assigned a seat, very stressful. The plane was delayed. Overall not a great travel experience for a 44 minute flight.

The seats were not very comfortable and there were no TV screens. Boarding was pretty fast because there were so few people on such a small plane and I appreciated that they still gave us our snack and drinks, however I really wish they would come up with a good gluten-free snack.

Didn’t realize we couldn’t actually get the full food menu while on-board. I saw that pre-ordering was available but didn’t realize the impact. Also didn’t know there weren’t entertainment devices on board had to bring your own device which I would’ve preferred to have clarity about ahead of time.

Boarding passes could not be received online, even after online check-in. While they appeared on the Alaska.com app, they did not transfer to inbox or messages and were not available at all on the Alaska.com app following the check-in process. There was no choice other than to get boarding passes at the airport counter.

Comfort level was below par. Food selection was non-existent. Paying $35 for 1st bag is never appreciated. I will not fly them again. I am actually trying to change my return flight.

Flight was on time. Crew was helping & seat were comfortable.

Great airline attendants. However I could not get the entertainment to work on the app

Was late but $50 voucher was great benefit of the summit card.

Every thing is on time, boarding, landing nice and smooth. But No tv? No food for 6 hours flight?

I always choose Alaska when I can. Every thing seems to run more efficiently with them.

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Great. I had to modify a flight. That was easy and free. Thank You

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

The pilot greased the landing and the crew was fantastic.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

delayed due to weather. Could not communicate with family since the wifi was broken

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.
