Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

The 1st class male crew member was very pleasant - the short female with round glasses , maybe in 50’s had no personality- never spoke when delivering my food, drink, & never smiled the whole trip! In fact looked annoyed when the boarding proses was happening- I would never hire this woman - unfriendly . Have never dealt with a crew member like her-

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

nothing Delta could do... the person sitting next to me was huge and overflowing into my seat

Crew was great! I need wheelchair assistance and they knew who I was and updated me that my chair was on its way and to just hang tight. There was some turbulence but the captain announced we would be going thru it and he handled the plane well. Landing was soft and his.

Aircraft very cramped. Check-in was great with an agent helping us. Food was almost non-existent. Pre-flight went well once I got the app reloaded on my phone since we don’t fly much anymore.

The Wi-Fi was unavailable on this flight for some reason.

That flight was smooth, and staff we courteous. it was a full flight so very tight. The boarding through security was not properly controlled. it was rushed and the scanning process for our bags, etc. was pilling up at the other end with no time to empty our belonging my personal items almost toppled over on the floor if i hadn't caught it rapidly. Was it just that time, or always like this - cant say. other than that all else was fine.

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

Paid WiFi was only available for a few minutes. Avoid at all costs.

It was terrible because the flight was delayed for 3 hours.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

Did not like the seat spacing. The seat was very narrow and tight.

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average, Air canada food was much better than united.

The flight was clean and on time, the crew were all very nice and we got the seats we booked. Plenty of food and beverages. The seats are too close so it’s very difficult to try and sleep comfortably.

Any flight that gets from point A to B with no drama is excellent.

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.

Delayed so that missed connecting flight. Connecting flight was also delayed on the tarmac but they closed the gate before the rescheduled time.

Took off over an hour late with multiple mechanical issues. Gate agent in Dallas was lazy and was slow as molasses. Had a line 10 people long. Spirit bad..

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Flight was delayed until Next day as crew timed out

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

I was able to get on standby with relative ease

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.

Kayak does not know that spirit airlines charged me $70 to fly. But the bag check-in was $89 each way. This is false advertising to lure people. Spirit airlines sends bunch of emails after flight purchases to buy wifi, better seats, priority boarding, secure reserved seats. This is false advertising. Up front pricing. I would of flown jet blue or Alaska airlines.

Every interaction the airline seems to want to find a different way to extract more money from you. The second leg of our journey they wouldn't let us board the plane without taking another $99 for a bag we asked about at the ticket counter and boarded with on the first leg of our journey. Horrible airline, poor culture. Not flying Spirit again.

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.

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(

Frontier is a crappy airline nothing about it is honest

If you don’t check in 24 hours in advance, they will charge you $110 to check your bag instead of the $30. I did not get an email with this information and did not check in. In addition, my flight home was cancelled at layover and I had to spend the night in the airport, and then have another layover at another airport before making it home. Will not fly frontier again.

Crew members are very rude and not cooperate with passengers.

30 minute delay due to boarding and settling of a family.

I hope to avoid flying with them in the future. First flight got cancelled then got stuck with a 13 hour layover in Denver. The process was long and frustrating to many people.

Flight was delayed on the runway for 40 minutes the crew did not even offer even water to passengers to compensate for the flight delayed. The flight was delayed due to aircraft mechanical issues. Worst customer service ever

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.

They changed my flight and did not want to accommodate me or try to help me in any way. They do not care about their customers.
