Delays from an earlier flight getting in and then maintenance delays. It was an overcrowded, uncomfortable flight. We didn't even get an apology from it being over 40 minutes late. Then you want us to buy tv? I'm thinking of flying Jet Blue next time!

Friendly flight attendants and nice to kids

Being held inside the plane for a total of 5:30 hours before taking off. Even if there were several concurring factors, it it necessary to find a better procedure in order to avoid keeping passangers inside a plane with the prospect of taking off in the next half hour repeated every half hour! For the ones of us traveling with children it is even worse, and becomes a real nightmare.

I do not like the two hour delay, after a hour maybe consider getting another plane.

Nothing aside from that the flight wasn’t crowded so I didn’t have someone next to me which was a plus.

Funky smell in plane something like artificial strawberry, farts and mildew. Crappy plane overall. Old and no power at seats. Horrible in flight entertainment for a long haul with no individual screens. American used to be so good and now it’s aweful.

The fact that my checked baggage is confusing when they charged me it was only for one way. I was billed and then noticed it was only one way, so I had to re enter my credit card info twice. Seems to me they should assume I will be bringing back my suitcase and contents rather than that I would be leaving it.

Flight 1039 dec 16 was delayed due to late inbound arrival to Aruba. United gave the reason "delayed Maintenance" which United denied as mechanical failure. We missed connected flight to Albany. United gave us only option: morning flight to Washington and then To Albany which is inacceptable option. We took rental car. Also: Workers at Newark do not coordinate. Super Slow and give disinformation.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
