Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

They did a fine job. Can't wait to use Delta in the future.

Seat back monitors and outlets were dead and not working.

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Boarding super slow with people allowed to linger in aisles

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

First time travel in economy and the worst experience I ever had ! Shame on paying 600 dollars to be in a tuna can ! Service was terrible no even water no even class no even matters your flight attendants were lazy and sloppy very bad experience! After all these years traveling in first and once I try this cause I need to go to a destination for an emergency wow shame on you !

Everything was smooth and easy to fly. No complains and a lot of thanks!

The net issue I had was with the gate agent. We had added a carryon to our boarding pass when we checked bags. When I got to the boarding gate the agent was rude asking why I had a backpack - I said I added it - even had an orange tag on it. She ripped my tag off and swung her monitor around to show me how she was right- saying it isn’t wasn’t listed - only a checked bag. I explained again that I wasn’t sure what the issue was but I wouldn’t have an orange tag if I hadn’t added it. Then she finally checked my husband’s boarding pass and found that the agent at checkin had added my carryon to his boarding pass instead of mine. She sent me on my way without my orange tag. Was a bit embarrassing for me the tone she used with me assuming I was trying to get away with something.

Gate agent asked if I could switch seats so a family could sit together. Agent moved me to a seat in the front of the plane, no charge. It was easy. The agent did a great job.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

Every Allegiant Air flight I've ever taken has been delayed. This flight was delayed a full 2 hours. It was excuse after excuse after excuse. It was a flight from southern Florida. They made us board the plane on time, but made us wait for 2 hours on the tarmac. Because the engines were kept shut off, so was the air conditioning. One can only imagine how hot the air was in the cabin over those 2 hours on the tarmac, while in the hot Florida sun. Just terrible.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.

The flight was delayed 6 hours and we were only offered an $8 food credit. My husband stood in line to get the credit for 45 minutes and when he got close to the end of the line the computers went down.

Worst ever! Flight cancelled supposedly for weather even though we k ow of many others who flew into Bangor same time no problem. At the airport there was no customer service at all just refund and no possibility of rebook for 3-4 days. Aweful won’t fly with them again!!

It’s a budget airline so adjust expectations accordingly. Nothing is without a fee but such is necessary for tickets to remain so affordable.

No complaints. It’s a budget airline so can’t expect any frills.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

I liked everything about the flight. The service was excellent!

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Good. The wife was not working but then it got resolved.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

It was a good flight. Of course it was full, but it went well.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Me and my husband experienced very bad in American Airlines. We missed our flight going to Doha. The American Airlines was delayed we arrived already 10:27pm. Supposed to be 9:40 pm. So what they did they rebooked our flight and they gave us a hotel. When we arrived at the hotel the front desk said it was fully booked already. Oh my gosh! I said why did you accept the booking if it's fully booked. The guy said that's American Airlines they just book even it's already full. That's 2am already, we have nothing to do so, we decided to go another hotel. We pay the room, food and taxi. Pls give an action on this matter. Refund our expenses and give us more compensation. Not only our room, food, taxi but also our efforts, tiredness looking for a room that can accommodate us.

Horrible. Flight was delayed and very bumpy. I was super unhappy

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.

Absolutely filthy flight and not equipped for a trans US
