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.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

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 .

I paid $7,000 to fly round trip to Porto. I thought it was for business class. But on the leg from Miami to Newark, and again from Newark to Miami, i was in coach. One time in the middle seat of coach. From Newark to Porto I was in business class as expected, and it was fine. I fly to Portugal once per month, often paying $5,000 for business class. Usually i fly American Airlines. I'd be happy to fly more with United Airlines. But my experience was disappointing because i was put in the coach for almost half the flights.

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!

Poor. Crew allowed children to run around and scream and disturb passanger’s seats.

Nothing also dont give to people that disgusting blanket and pilow.

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

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.

It was a pretty smooth flight, I tend to get mini anxiety attacks during flights, however, this time was pretty smooth and I was able to relax. The only thing, I was having issues to connect to the Flyfi internet. I was not able to connect at all, I turned off my phone a couple times and didnt work.

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.

we were delayed because of some safety check that wasn't done or available

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.

Smooth flight staff very friendly and we arrived 15 mins earlier

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.

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 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!!!

Forgot my anxiety pills, crew didn’t knew what to do then few minutes after they gave me a bottle of water and told me to walk thru the hall. They should be trained for this kinds of situations cause it really would help someone. Tips: bottle of water (airports should allow passengers at least having them thru) for this kinds of situations. Alcohol wipes just in case they don’t have. Tap water on skin (preferably little cold or a normal temperature) this will help.

All of our flights were canceled, though every other airline was flying out and in

didn't order food on board. there's no way to hold a water botton on the way. otherwise it was a pleasant flight, thanks to the crew.

Even though there was a delay the crew was exceptional.

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.
