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.

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.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Too many fees (but that seems to apply to all airlines nowadays)

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.

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.

delayed and had to switch planes because first plane was broken.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

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.

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

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.

My experience was better than expected. What I did find not so great was the seats. Very little room, they did not recline and the tray table was the size of a post card. There was no food to try, just standard snacks that you had to pay for and I don’t know of any entertainment. I would fly again even though everything was an upcharge. Flight was on time with little disturbance

Compared to other airlines, this was a bit sub par in my honest opinion. My flight back was better than my departure flight.

thy don't even ofer water we have to buy it for $4.49 and paid for our cary on bags $100 each we never will fly in this company again.

Super cool and laid back, three lovely ladies. Couldn’t ask for better service.

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

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….

See my previous comment which is mostly about our flight from Phoenix to SFO
