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.

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.

Poor food for vegetarians. Also the overhead space was not locked properly. Suddenly, it opened and my carry on fell out. Luckily, it didn’t hit my husband who had the aisle seat or anyone else. However, I am upset because my laptop was inside this and may be damaged now.

The flights were good. The cancellation was handled poorly.

AA’s flight was canceled from Seattle to JFK. The flight was then rescheduled to Newark and then Orly. The main problem is that the change didn’t include the infant on lap ticket and ended up with 2 hours in Newark trying to rectify the situation.

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.

Flight was very late. Reason given was a mechanical issue but last minute boarding was people whose flight out of Gatwick was cancelled and they were bussed to Heathrow so I suspect that was the real cause for the delay or at least a part of it

The ground crew was very curt and non helpful. Apparently there was a rule that laptops had to be in the checked baggage. The ground crew could have been more courteous with passengers for whom this was a great inconvenience. In my specific case, the person checking me in labelled my bad "Long Stay" instead of "Priority" because they misread the instructions on the computer. The person would not listen to me and would not re-check his potential error....I fly British Airways all the time and that did not seem to make a difference in his demeanor

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.

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.
