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.

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Confusing. Delay updates were out of whack At one point it said my flight was 25 hours. Three gate changes and two delays only to change back to original departure time. Gate announcer and on board flight attendant (Alejandro) making the announcements was impossible to understand due to accent and speed of speech. After beverage service the rear flight attendants sat back there on their phones. No refills no checking in, one sweep through for trash collection. Very impersonal. Bring back Coke products

Delayed departure. Delayed after landing pulling into gate. Delay due to sky bridge malfunction

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

Everything was good except for deplaning in NY. Took way too long!!

Jet Blue keeps getting iit wrong. 4 hour mechanical delay followed by terrible boarding experience. This is my third horrific jet blue flight in 2024. I am going to try to avoid this loser in the sky

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

My experience with JetBlue was fantastic! The service was top-notch, the flight was smooth, and the staff were friendly and helpful. I would definitely fly with them again.

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

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.

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

The agents at the gate were rude. The stwards were pleasant. The seats were comfortable. The tray table had crumbs on it. A passenger talked constantlt and very loudly for the entire flight annoying many passengers. The stewards did not ask her to speak in a lower voice but my travel partner did.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

One of the worst flights I have ever taken Delayed over an hour without communication from the crew; very scary Entertainment not working Crew NASTY cabin cold

May never fly American again Delay in take off WITHOUT EXPLANATION Cabin freezing Crew NASTY entertainment did not work entire flight

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

Flight was delayed due to crew not being there, besides that it was a normal flight.

We were re routed due to a flight cancellation. We did not fly out of Miami. We originally booked first class and were moved to coach without being compensated.

The whole day was a nightmare. Flight extremely late. Boarding was a mess of a nightmare.

Never been on this flight as i had missed it due to delayed connecting flight

Missed our departing flight due to poor baggage drop staff. At the airport with 2 & 1/2 hours to spare and waited in bag check in until 15 minutes prior to gates closing before baggage staff asked us to move to the front of the line. We weren’t the only passengers that missed the flight. Poor organizational operations by Spirit staff. Otherwise , the return trip was fine.

Worst airline experience ever. Lost my IPad going thru security. Charged for my dog carriage at the gate not at ticket counter. Gave away my seat 6D. Expressed I wanted my seat back after charging me 99 for dog carriage. Should have thrown it out. Had a 16 yr old Yorkie heading to Boston after being a snowbird. Seats small. Very bad experience. Still don’t have my IPad. Horrible

The boarding gate was moved so many times that I missed my flight. No attendants would help me. The wrong gate was even on my boarding pass. I had to repurchase everything. I’ll never fly again. Really a terrible day as I had planned to see a former student who is dying in Louisville Never ever will I forget that day. Your airline is totally uncaring.

Hated it I would not use Kayak or Spirit ever again.

Flight kept delayed from morning to late afternoon so I had to make other arrangements

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

My wife and I are both handicapped and at boarding they upgraded us to a seat closer to the front rather than all the way towards the back. Much appreciated.

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

Crew members are very rude and not cooperate with passengers.

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

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.

Well, I didn’t have food! So NA wasn’t an option. I’ll be back!

First time flying with Frontier . From buying tickets ,getting boarding pass and boarding plane was super easy. Definitely would fly again with Frontier .

Our flight was on time and unremarkable which I'm grateful for, as it is not the norm traveling these days. Frontier is a low-cost carrier and it really shows when compared to other "normal" carriers. They don't even give you water during the flight. The coach seats are decent, however it was not as clean as it should be. We had crumbs all over the floor by our seats.

They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.

they charge too much when you arrive in the air port
