I didn't go from Reno to Phoenix I ended up going from Reno to Dallas to Tucson because my flight rebooked because my Amtrak was late I tried notifying you guys I also don't know what you ask me about my flight because you guys didn't book my flight

A chaotic and uncomfortable experience from start to finish. The boarding process was a disaster; despite group numbers, it was a free-for-all that the staff failed to manage (especially after group 5). Once on board, the "entertainment" was non-existent. There are no seatback screens, and the mobile app selection is incredibly thin. The hardware is severely dated. My seat had zero cushioning left—it felt like sitting on a hard board for the entire flight—and the legroom was cramped. To make matters worse, the bathroom was repulsive, with toilet paper, soiled paper towels and liquid/pee all over the floor. When I did interact with the crew, they provided the absolute bare minimum and made me feel like an inconvenience for asking for anything. Avoid this flight if you can.

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

there are no options s for snack besides cookies would ve nice to have a salty option n

We left at 1030 am pacific from LA and supposed to land at 7 pm Eastern in NY. They made a detour, stopped in Philadelphia and didn’t land till 1130 PM Eastern!!! Worst flight experience with no pilot communication with no explanation as to what was going on. Everyone was very frustrated to say the least.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

It was canceled at the last minute. While I was literally at the airport. Messed my entire trip up.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.
