Good, but I had 3 hour layover after getting to phx from Everett. Can’t American have an earlier flight?

Pretzels are awful. Empty calories. There’s gotta be something else.

Very comfortable - thanks. Only small criticism was the delay in disembarking caused by the passengers in the front two rows chatting to the cabin crew.

Probably one of the best flights I’ve had! From entering the airport, to boarding to landing.

My as.com flight was too short to care (Tucson to phoenix) or comment.

It was a little chilly on the ride. The entertainment was the book I brought, and it was excellent.

Crew was great, flight was uneventful (which is what you want!), would like media in the seat backs in all airplanes ..but all in all it was a good flight experience.

Unfortunately, an issue occurred where a delay impeded me from making my connection in LA. I couldn't get a flight home until 10 hours after my originally scheduled flight. Once I finally made it to DFW for my connecting flight, my next flight was delayed. I was supposed to be home on 12/23 at 9:00 p.m. I didn't make it home until 12/24 at 11:00 a.m. I was given the choice to either take a flight the next day or the flight that way 10 hours later. I wasn't given an option for a hotel if I stayed overnight. I was also denied the ability to go to the Alaska Lounge due to the delay. It was a very uncomfortable experience. The only seat I was able to get on the next flight was in a row where the seats couldn't recline. After an extended wait at the airport, this was very frustrating!

Paid for first class, but the flight attendant for first class did the minimum required. She really ever came to pick up the trash, and never asked if we needed anything. Every person had to ring for the flight attendants if they wanted any extra drinks. When I went back to use the restroom, she was just sitting on her phone.

We don't have food or entertainment on this flight. We were late boarding but then arrived in Yakima early. Kayak sent me a delay notice but we weren't delayed.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We arrived early and finally made it to our gate almost an hour after.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight crew was fantastic! Which the seats had a small TV.

The flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad

Very easy with the app to board and staff skills

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

My experience with the phoenix airport was terrible, the personnel lay the ticket counter charged me for a carry on that fit in the carry on size box, and the two women I spoke with were terribly rude and not willing to help.,,, there was one lady “candy” on the flight crew that was amazing and is the only reason I stayed on the flight at all, because the other stewards helping people to get seated on the plane were terrible

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

The seats were extremely hard and uncomfortable, even for a budget airline.

The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.

Charging $74 for one checked bag is outrageous. I will never fly Frontier again.

Boarding was very well executed. Got my bag right away.

I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.
