Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

OK, we were delayed and had to de plane and reboard.

Both my flight where delayed Had 25min to make it to my transfer flight

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.

Qatar does not answer phone calls and communicate with travelers about trip cancellations

The seats have so much room. They give great free snacks. Staff was so nice.

Very smooth flight, good legroom with the "even more room" seats. Entertainment choice was excellent, wifi on board, plane was modern. Pilot got a round of applause for a smooth landing in very blustery conditions. Love flying with them. Check in was OK too. We were too early so we had to wait until groundstaff showed up 3hrs before the flight.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

They initially informed us that the flight was delayed, but only after waiting an hour for updates. In any event, the flight was canceled, but the way it was handled was really poor and egregious. I feel they handled the situation of informing travelers very irresponsibly. I sat in a wheelchair at the airport for over four hours before finally being told that the flight was canceled.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

Really good. I accidentally left my duffel on the plane and the reps were so friendly in retrieving it.

Our flight was delayed 3 times and this is why I am giving such low reviews. Everything else was okay but being in the airport at 4:30pm for my initial flight at 7pm to not leave until after 9:30pm is insane,

The crew was excellent and overall the flight was good. No complaints.

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.

My seat was assigned last row behind restrooms No legroom’s I’m very Pettit Still was not comfortable Food choice was excellent

There was free WiFi (definitely a plus), but the flight was delayed 45 minutes waiting on a catering truck that never arrived. The pilot said there would be food vouchers given out at the end of the gangway to make up for the inconvenience, but there was no one offering those. Delay made me late for work!

Overall it was a good flight. Because we traveled on a Saturday we were upgraded to FC since my wife and I are both Executive Platinum. The only areas for improvement we noted are better snack assortment and perhaps a little nicer plane as American is flying some older planes now. Everything else on this flight was excellent, which is frankly not the norm for American since we have had multiple issues on prior AA flights.

The smell from the bathroom kept wafting through the cabin. It made people sick.

The seats are too uncomfortable for anyone over 5ft 8in. I'm 5'10" with a back and hip issue and I was in pai for the full duration of the flight.

Delayed an hour due to operational issues. Minimal apologies or care for the significant inconvenience caused. Landed at nearly 1am and they still couldn’t find ground staff to get us off the plane promptly.

Length of flight was fine Delay of over 3 hours was very bad!! Flight down was delayed 1.5 hours

I’m still waiting to get on the flight. No one knows what’s happening. The passengers have gotten no updates. We have been up all night and waiting at the airport. This is no way to operate and we should be refunded for this lack of respect for their passengers.

Flight was delayed, then undelayed, then delayed again. Gate was changed to the other side of the airport. Horrible seats with no screens. Spirit os truly awful, even for a budget option.

When I arrived at the airport at 4:00 in the morning, I was notified that I "hadn't paid" for my ticket (I had paid and had a boarding pass). Then I was told that while I had paid, the ticket was $600 more than it actually was, and that I needed to pay that so I could board. None of this was true, of course, but it took 20 minutes, two crew members behind the desk, and one on the phone to clear up.

I have to wait for the flight for 3 hours. The gate was switching for 5 times. Made feel frustrated. Delays took all my sleep. I went to work without any sleep.

Spirit Airlines at Laguardia is a small terminal so it is quick to get to your gate and to get your luggage. The flight is short enough to orlando and the price was very inexpensive. The seats do not move so you can't recline. Drinks and snakcks should be complimentary.

I was double booked for my ticket- they have record of it and admitted to their error but wouldn’t let me board until I paid once again for the fare- have documentation of their mistake -

Horrible experience!! In the meantime we were in Philadelphia they didn’t give us some water and the information about the fly on the plane was without empathy!!! Plus the fly started with delay!! So very unhappy moment!!!

Flight got cancelled 1.5 hours prior to gate open and logistics of travel got delayed.

Spirit loves to pick and choose when to harass you about your personal item. I’ve flown numerous times with the same bag with no problem yet flying out of Orlando they forced me to pay $99 for a carry on and then ran out of overhead space. Do better!

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Plane and crew on board were fine. Everything else was terrible.

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

Flight got delayed for 5 hours no good explanation was offered ;(

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

The experience was good. No frills but I got there safe and sound and on time.

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

After boarding and un-boarding twice over 6+hours, the flight was canceled.
