Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Wifi wasn’t working well so we couldn't view any media.

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

Crew was great. Friendly, calm, interesting, happy to be there. That makes a huge difference. Plane was very quiet. Also quite empty so I had three seats to sleep across

Had assistance at airport getting from arrivals gate to departure gate; I couldn't have managed without that extra help. Thank you Delta.

They charge me for the luggage which is was included on the ticket

More space in the cabin. The guy in front of me leaned his seat back and I felt he was sitting in my lap.

Was a great smooth flight from Detroit to San Diego.

Late flight, always blaming the flight crew, stale almonds, pushy people. Why don’t they have the people sitting in the back board first? So much easier getting through an empty plane! Duh!!

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

American Airlines is awful!! Will never fly with them again. Connection flight left early leaving 22 people in Charlotte with no way to get to Key West for 24 hours. Would not provide hotel or any other accommodations. Bags were delayed two days.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

They stuck us with multiple extra fees. I will never fly spirit again

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

They charged me 212.00 for a heavy check in bag at the gate. The pricing and process was so confusing - as if it was designed to purposefully gouge customers who need to board plane. That experience combined with the outrageous price charged will prevent me from ever flying Spirit again. And I’ll be sure to tell the story to anyone who cares to hear.

They didn’t let me get my boarding pass through the app because I have a lap infant. The ticket said to see a gate agent but there was no gate agent available. I was supposed to go to the kiosk. Ended up missing my flight and they said that I never checked in to my flight so there was nothing that could be done. I will never fly spirit again. Not even worth the hassle and poor customer service.

The text told me it was changed to Terminal E and Gate D5. But with no one on site to ask questions there was confusion on where to go as all the gates were E's. Then we took the skyline to the D area. We left to get something to eat. No announcement was made but my daughter happened to asked and they told her our gate was moved to D12. I will not fly Spirit again.

The agent at the check in desk was absolutely rude. The rest of the team after that was good, but the check in process at LAS was miserable. The woman at the desk spoke like we were stupid and was rude throughout the process.

Its so random that they only allow 40 pounds on checked bags when all airlines take 55. They then charge you for each 10 extra pounds, so my checked suitcase was $130 and the flight $30 ... its like whattt, im for sure not traveling with Spirit again

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

So bad. The check in process was laborious and the check in agent didn't seem to know how to manage the process efficiently and was confused about how to check in my son's sports equipment. The baggage fees were outrageous and so expensive. $90 for a carry on bag? And $200 additional for 2 check ins. The security lines were insanely long and the terminal was not very nice in the Spirit area. $5 for a water on board. It was my first and last time flying Spirit - I tried to save $ by flying them due to the accommodating schedule but I should have paid for Southwest, because it would've actually ended up less expensive due to the free bags with Southwest. There were no charging ports on the airplane, no wifi and really uncomfortable seating. The flight crew were great though, courteous and efficient in their boarding. Flight was delayed 1 hour, but we made up 15 minutes in flight.

Passengers play their phones so everyone can hear them. No one tells them to use earbuds. Very annoying and unenjoyable.

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

Worst experience I have seen. The flight was cancelled without any reason.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

The Frontier app wasn’t working. So I could not pay for a carry on the week prior to flying. They charged me 99$ at the gate to carry on a duffle bag.

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

Plane could have been more on time. More leg room .

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….
