Not much.

The flight was late due to maintenance and caused us to miss our connecting flight to Chicago. American Airlines customer assistance at the airport was absolutely terrible. They were rude and inconsiderate as they kept suggesting to fly standby. We shouldn't have to fly standby when it wasn't our fault why were late. They told us our bags would be ok going to Chicago and they we would make the flight, but we did not. I do not know why didn't wait for us considering there were 8 others that also missed the connecting flight. We had to fly to Denver and stay overnight with no luggage and catch a 7:00am flight to Chicago. The last surprise I received was my damaged bag when I got back to Chicago. Thank you for making this trip memorable in a terrible way. I will never book or recommend Kayak or use American Airlines again.

The seats actually had individual screens, which was a very nice surprise. There’s a decent movie collection. alao the flight attendants were very nice and friendly.

The tv show selection is quite poor. Also, like the previous flight, my husband and I weren’t seated together (not even in the same row) and when I tried to change it online, the entire flight showed as booked. However once on board there were clearly a number of empty seats.

Seats were comfy.

Delayed 2 hours, crew handled it pretty unprofessionally. Once on the flight from Denver to Boston, the crew were rude to me every time they spoke to me. They repeatedly bumped into me without apology and repeatedly told me to do things I had already done like put my seat up and buckle my seat belt (but strangely didn't do the same to the older couple next to me that did have their belts unbuckled). The computer screens barely worked and the map kept flashing to advertisements telling me not to watch the map. I literally just wanted to watch the map. I would not fly jet blue again because of this experience

Boarding seemed to be pretty efficient, especially compared to my most recent experiences on American. Flight was smooth (of course, airline doesn't have much to do with that). Got to my destination along with my luggage. Did not feel cramped on the plane and I was in a regular seat. Did not feel like I had to spend through the nose to just have a passable experience.

Flight was almost 2 hours delayed. Plane felt a little shabby. Sometimes I found it hard to understand the flight attendant who did most of the announcements - she had an accent, which would have been fine, except that she either spoke too fast, or was mumbling. All that together, made it hard to understand her. Pilots never spoke to us. Not once.

On time in spite of a late start Gate attendants were nice and helpful Comfortable as is possible in economy without spending a lot more money. Food (pretzels and drinks) as good as possible without spending more money. (I remember the good old days when you got much more in seating and food for your money)

This flight I had a window seat and I felt like I couldn't get up to stretch my legs or use the bathroom. (I am 70 and 4 hours is too long to sit) I usually get an isle seat but ALWAYS have to give up my bag at the gate - my bag which you tell me I can bring ON the plane with me. I do not like having to waste time claiming my bag that you told me I could have with me on the plane. I can pay $25 for that privilege!! The flight attendants always seem like they have their defenses up. One even held up the people trying to board so she could serve a drink to someone in first class. REALLY?? They couldn't wait till the plane was loaded?? I gave this flight a 'good' rating because it was mostly as good as it is going to get with economy passengers needs stripped to the bare minimum.

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,
