My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

Horrible. I likely will have to spend several thousand dollars to rebook my international flights, due to their delays, plus a hotel in SF. I can’t wait to never fly them again!

Quick easy boarding. Airport was unprepared for early landing and we were waiting in the plane for 20 minutes before getting a gate.

It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

Staff seemed genuinely nice, not just going through the motions.

I would have rated the entire experience much better were it not for two things: 1. There was inconsistency between what we were told once on the plane vs. the answer I received to the question about "spreading out" from our assigned seats because the flight was sparsely populated, and the entire row we were in was empty but for us. I asked about one of us moving over one seat to make more room for us; before getting on the plane, I was told we could, which seemed like a sensible answer. Once on the plane, it was announced that we needed to stay in our assigned seats despite all of the empty space in our row, which seemed unneccessarily restrictive. 2. To add to the discomfort, we sat on the tarmac once the plane landed in Burbank for over half an hour waiting for a gate to become available. During that time we had to remain seated and buckled in, which was becoming more difficult as time dragged on, especially for my wife. If all of this was due to regulations, that may mitigate the sense of "needless" restriction somewhat, but it points to a need to make regulations less restrictive where it is not appropriate for the current conditions. The crew was not "nasty" about the restrictions, so I do not resent their actions, but it certainly would have been a much more pleasant flight if we had a few more options when it comes to comfort.

The seat side plug ins didn’t work in my row, and I ran out of things to do since my iPad and iPhone ran out of juice. The flight attendant offered me a free drink but I don’t drink. I suggested a free snack box instead and she just shrugged and walked off. Why do us non-drinkers get the short end of the stick?

Flight left two hours late with no real explanation and they inexplicably had the heat running on the flight as well

I like Alaska Air fine. Great crew. Late departure still arrived on time.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Crew was not friendly when I went to request a seat change.

Really impressive staff at airport and on plane, especially given how busy it was

Was a great smooth flight from Detroit to San Diego.

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)

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

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.

We were told there would be no food/beverage service due to turbulence. There was very little turbulence on the 2+ hour flight. I was in First Class and thought they could have done a quick service after take off as they had a quite bit of time before we would be reaching the predicted turbulent area. They could have at least passed out a quick bag of pretzels.

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

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.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

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
