The boarding process could be clearer, there's never a call for group f

I bought tickets MONTHS ago for a flight that left SAN at 14:30. That is what it says on our tickets. I was never notified of any time changes. During online check-in. I discovered the flight time had been changed to 15:45. This was unacceptable and had I been notified, I would have changed flights, or airlines. That departure time was unworkable with our plans. We called Alaska and asked for an explanation. They said flight time was changed 11/08/25. No proof of notification could be offered. We asked to be moved to an earlier flight. After much pleading, the rep said she would allow a “one time exception..” While I appreciate being moved, this was YOUR fault Alaska Airlines.

Liked the attention and speed when getting wheelchair..........Was assured by phone that my needs would be taken care of and they were with my name.

Crew very courteous. Boarding was great. Slow to get baggage at Denver.

The tray wasn’t cleaned, it had crumbs from the last flight Other than that it was very comfortable by

Experience overall was great, we didn’t land upside down like a Delta plane once did. The entertainment section didn’t apply for me, but I put excellent I think anyway.

Representatives both at the gate and on the plane have zero interest in helping you! It’s really unfortunate…

The planes were in very nice condition. Comfortable enough leg room. I had a very quick connection on my return home I made it just fine and so did my luggage!!

Attentive, caring. Loved the communication in the app even before boarding and while on plane from pilots.

We left late; had to land in Minneapolis unscheduled to refuel and then landed in interior instead of lax at 2am......

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Flight was delayed due to crew being not on time

Flight crew issues delayed my flight by 2 1/2 hours. Causing me to miss my connection.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

Never got on it. Was re-routed through Detroit and am still in airports 12 hours later waiting for my connecting plane to arrive.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

Very Very late. Subsequent flights left an hour before ours

This is my worse experience with Delta. My colleagues and I were traveling to ICT for work. Usually we connect in Dallas, but this year we decided to book with Delta and connect in Atlanta. We were excited to fly with Delta because we hear great things and Delta is one of my top choices when choosing an airline for travel. On the connecting flights to and from Wichita/Atlanta - it felt hot and uncomfortable on the plane. The plane to ICT was smaller and older and did not have any wi-fi or entertainment. The most terrible experience was at boarding in Atlanta both times traveling to Wichita and then back to Tampa. First on our flight from ATL to ICT - the attendant scanning our boarding pass made us go back to the line when we went up to scan our passes to wait. After a few minutes, she allowed us to come back up to scan but then she asked what boarding zone we were. We told her zone 5, and since we were standing on the wrong side of the small rope partition, she made us go back to stand on the right side. There was another gentleman that came up to board and scan his pass, and she mentioned he was also on the wrong side but she let him go through. Our group had to walk back and forth for no reason, causing an unnecessary delay to board the plane. We have never experienced anything like this, especially when the boarding area was completely empty and everyone already boarded since boarding was earlier than the original boarding time. On our flight from ATL to TPA, the attendants scanning our boarding passes had us scan our passes twice, not explaining to us what was going on. They automatically started tagging our carry on bags and did not explain to us or tell us what was going on and why this was happening. Obviously we knew our bags were being forced to check in but with no reason. There was no announcement or mention and I have never had anyone force me to check in my bag before boarding the plane. We assumed the overhead bins were full but when we boarded the plane, there was a lot of empty bins and a lot of spaces to put our bags. We all were disappointed and frustrated with Delta and will be hesitant to fly Delta again or anytime soon.

Boarding and crew were fantastic, but I paid for a window seat with no window. Seat 11D on a CRJ-900 apparently does not have a window. Lesson learned.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

it was a very short flight so my expectations were low.

As great a red-eye flight as red-eye flights can be.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Superb. Staff great. Great flight. As with other airlines, seating too tight and restrictive.

There is not one likable thing about this airline. It’s starts with the deceptive pricing and continues through the whole flight. The worst staff I’ve ever experienced way over priced bags absolutely no food or drink (unacceptable and you should be embarrassed) the seats are cramped and uncomfortable there is no entertainment there is nothing about this trash airline that constitutes any amount of money. It’s worse than spirit and way more expensive it is disgraceful. Do not travel with Allegiant I repeat do not bother no matter what they say the price is it is never ever going to be the right choice I’m mind blown at how awful the entire experience was I’m embarrassed that I chose so poorly I cannot reiterate enough how beyond horrible this company and its staff are, not one person on this flight or at the airport is qualified to sweep up trash on a city sidewalk they should certainly never be given any job that requires a brain or manners or communication with human beings, what a disgrace to the human race. Your criminal chiselers and should be put out to pasture

Great flight. Friendly staff. Free snacks and drinks would be nice. I would love fewer taxes and fees added on.

My 90 year old father flew with me. He needed wheel chair assistance and is nearly deaf. The staff was amazing with him.

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.
