The crew was very helpful at each stop even though they weren't responsible for the disasters.

Initially we thought we were flying with British Airways. We then had to do some digging to realize it was all out of American Airlines. Then we couldn't get proper boarding passes and luggage tags until one of the crew members spent a significant amount of time untangling each leg of our trip so they were in the proper order. We got delayed by 4 hours in Chicago and missed our connection in Manchester. We had another 5 hour wait there. By the time we got to Dublin, our bags didn't also arrive. After almost 24 hours of travel, we arrived but without all of our stuff.

There was nothing too bad other than I wasn't able to check in online bc our first leg of the flight was operated by American Airlines. But there wasn't anything that really stood out that would make me want to fly them again other than it was the best price.

Way off schedule, way to tight of space, no way to sleep being such a late flight! As far as a beverage, they were out of everything!! Nice air line for quick trips,but to fly for 4 hrs at night from leaving at 12;00am, just impossible to sleep or really relax.

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.

Airport person with wheelchair at Denver was extremely helpful getting a disabled co-travelor from gate b85 to gate b28 in record time to catch the flight to Chicago. A BIG Thank You to the agent in charge of boarding for getting the three of us sitting together.

The direct tv screen couldn’t be shutoff. With a plan as big as a 757 there should be a beverage cart per section of the aircraft otherwise passengers at the far end are wondering why they’re being left out.

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.

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.
