The low fare was the best part of the flight, but I later found that it came at a cost!!!!

First of all the Crew was rude and their lack of patience was obvious, the flight was delayed and was no fault of any of the passengers yet we were made to feel as if it was our ( passengers) fault. Secondly, the air was turned down, I guess to conserve fuel, and the plane was unbearably hot, And at no time was food offered for purchase or even a beverage service. I have flow AA for 20+ years and this was the FURST flight I have ever experienced. Sadly I believe it will be my last!!!!

I liked the check-in kiosk, but only because I had no bags to check. I liked being able to choose my own seat. I liked that the flight was uneventful. I liked the staff at all stages, they were friendly and helpful.

They made me shove my purse into my knapsack to fit within their two bag policy. That's a first for me. My Delta flight did not do that.

Friendly, helpful flight attendants. Flight left and arrived on time, despite being completely full (asking for volunteers to bump). Offered to gate-check our carry-on bags for free to alleviate crowding of overhead bins was fine for us since we already had checked baggage.

If you don't pay for the premium seats, the legroom is pretty tight. I'm only 5'8" and I felt it -- if you're 6'+ you better pay for it. This aircraft had screens, but not individual ones so you're stuck watching whatever sitcom replay they pick, although there is a moderate selection of other music. I've been on a newer aircraft with the in-seat power and interactive screens so I know how good it can be, so this was a little disappointing.

I've always wanted to go to all five Manhattan boroughs in one day. Thanks to Delta, that happened.

The plane broke down as we were about to take off. Delta rebooked everyone on to new flights because it was pretty obvious that plane was not going to be fixed in time. The crew did their best given the situation. The situation was absolute bs though - we had to take a cab to JFK for our new flight and do the whole security thing again and all that annoying stuff. Thanks for wasting 8 hours of my life, Delta.

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,
