Cons: Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had.

Okay 4.0

Pros: Friendly crew. Due to the apparent regularity of excessively delayed American Airlines flights, they had the staff at O'hare bring a cart filled with cheap canned juice and Diet Soda to lessen the blow of their consistently delayed flights.

Cons: Like every other American Airlines flight I've ever been on, it was delayed. Including the American flight from Denver to Chicago. We pay entirely too much money to these airlines for them to deliver such painfully mediocre service and consistently delayed flights. I recommend that this airline do a SERIOUS audit of their Preventative Maintenance/Service division across their hubs. If I fly American, I would bet my entire checking account that the plane will be delayed well over 2 hours.

Cons: We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner.

Delta crew member in JFK was rude and unhelpful. The second agent (who ultimately booked our standby tickets for our original connecting flight) was more pleasant.

After being delayed for 2 hrs and 15 minutes, when we got to cruise altitude they asked us for money for water. Are you serious? Also i was told that same plane will depart from Denver to Phoenix.

Mediocre 2.0

Pros: We arrived

Cons: Two hour delay with no reason why which is a really big deal when you arrive at your destination at 1 in the morning and you need to be up to baptize a child at 8 the next morning.

Okay 5.0

Cons: Placed in middle seat with no options for isle or window due to my ticket. No problem with that if the people next to me were not so big. Young woman to my left by window was tall and broad and slept but took up all elbow and shoulder space. Guy to my right was very obese, sweaty so kept wiping his neck, head, and face with a cloth. Also had terrible body odor. I spent the entire flight in a narrow middle seat, hunching my shoulders due to lack of space. Both people taking up some of what little room I had.

Good 7.6

Pros: Everybody was very nice and the woman at the gate was very efficient at getting everyone assigned and through and up to date.

Cons: Quarters were just very cramped. The seat wasn't quite padded enough so my hips began to hurt.

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.
