Flight was 3 hours late so only had an OK experience

It was very cold because the air conditioner was on high power, and my son got sick.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

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

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

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.

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

I missed this flight due to delays on my previous flight.

The flight was sequentially delayed until it reached two hours. Apparently one pilot failed to show up.

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

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.

The flight was 6 hr late and then they blamed it on the weather. All of the other planes were coming and going fine.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Well, flight times cause some wait, but there were not times available and we understood. I didn't check any luggage, because it has become too expensive. I was able to add any extra items to my co-travellers check bags. [Luckily, this trip wasn't international.] Last, I hadn't flown AA domestically for a while, but partners and coworkers had warned me in advance that not all planes have monitors at every seat. Luckily, I was mostly prepared to use the in-flight entertainment and happy I was. The great: AA staff is always kind and comfort is way better than the budget airlines that I sometimes have to fly. I know my points and vouchers all expired over the last couple of years, but I still enjoy AA when I do fly with them. I also appreciate all of the locations we can go directly from pur home airport. Since we are traveling more now, I hope to take advantage.

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

I thought people that were clearly intoxicated were not allowed to board flights. But of course they let them and of course they sat directly behind us. Kicking seats being so loud you couldn’t hear yourself think. Cussing loudly telling a woman “she was going to punch her in the fucken face” for accidentally mixing her seat assignment up. These people should have been asked to get off the plane but no flight attendant cared. I don’t think I’ll be using spirit again. Better judgment needs to be used when letting people fly drunk.

Terrible legroom, seats do not recline, tray table the size of an iPhone, delayed flight, have to pay 5$ to get a cup of water onboard.

The flight was on time and nice as always for me with spirit but the cabin crew were not good. They left the lights on on a red eye for the entire flight.

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

The crew was the best and very accommodating I know you don't offer any complimentary items but water and coffee will not break the bank !!

My experience with Spirit was perfect. Did not expect it to be this good

My mother was HARASSED AND ACCOSTED by the gate agent for her bag. I pre purchased the bag fee and the gate agent made my 78 year old mother board, deplane, re pay for her bag fee and board again. The gate agent made my mother pick up her own bag and REFUSED to help her, she is an older woman who wasn’t bothering anyone on a flight that had maybe 30’total passengers. I am going to sue this airlines for their HORRIBLE customer service and treatment of my mother, and all this occurred the day after Mother’s Day!!!

For it to have left on time! Instead of two hours early with zero notice

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.

Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries. They dont really bother you about carry-on size, I brought a descent sized backpack and they didnt even check.

One gate agent in Sioux Falls ruined it for a few people on the flight. It was the usual, that personal item is too large, you are going to have to pay $100 to get it on the flight. One family with a baby were told that they had to have a passport for the baby to get on the flight. Also a Sheriff's Deputy needed to go on the airplane to return a lost cell phone to a minor on the flight. The gate agent would NOT let him go on without a boarding pass. I don't know who this moron was, but the sooner Frontier moves him where he can't interact with people, the better off they will be. Let's just say the deputy did the job that he needed to do and returned the phone to the minor on the plane, even with argument from a gate agent that thought he had way more power than he actually does. Very IRRITATING individual.

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

They never updated the boarding pass on their apps to show their delay

Online check-in was not user-friendly. Too many fees, not cost effective.

They wouldn’t let us on the flight even tho we were an hour early. No refund not even our bags that were prepaid

I brought a ticket and car rental through Travelocity. There was no where to add a KTN. So I thought i’d add it by looking up ticket on frontier website. I tried 3 times with the frontier chat bot to add my KTN it never updated my boarding pass. So then I tried showing up early to do it in person at the airport. The first employee update my ktn in the system and gave me a new boarding pass. I was sent back by tsa to join regular line. Then I was told to add my Ktn. It would cost me $25 extra. Given the length of the cue I did pay. Congratulations! BUT I will NEVER fly frontier again. Plus the plane was very old. It had actual ashtrays and old looking tray backs. Worst travel experience ever. Im warning my friends and family not to use frontier ever.

I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

Did not realize seats did not recline. Best to travel in an exit row... No question

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline
