On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

We had the best flight attendant ever! Her name was Sharon on Eandeavor / Delta Cnx, and she made the experience the best flight I've experienced. Thanks Sharon for being awesome!

The crew was late so we were delayed two hours. I find that extremely infuriating when you are a passenger and have to show up two hours before your flight. I also would lose my job if I was two hours late for a client.

I like how quick and efficient the boarding and check in process was.

I just wish that if I paid a little more for seats I should get more comfortable and roomier seats is all. Don’t make the seats sit so upright.

This flight was miserable. Seriously, one of the worst flight experiences I've ever had. The leg room was absurdly small. I'm not a tall person and I only had one inch in front of my legs. When the guy in front of me put his seat back it pressed into my knees. There wasn't enough space to bend down and untie my shoes, let alone get something out of my bag. My shoulder and knee were touching the guy next to me (a complete stranger) for the entire flight and there was nothing I could do about it. This was a red-eye but I absolutely could not sleep because it was so uncomfortable, so when we landed I had a terrible migraine and was nauseous and disoriented going through customs. I actually had to sit down in the airport because I though I was gonna pass out while trying to carry my bag, that's how shitty I felt after this flight. On top of that, not being able to sleep on the flight really messed up my sleep schedule and so jet lag from the time change has been made even worse, so I'm completely out of whack and its so much worse that it otherwise would have been because of the horrible flight. Also the food was gross and there wasn't enough of it. Even now, I don't think I have really communicated just how shitty this flight was. I was actually angry when I saw my seat upon boarding, and I'm still angry about it now.

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.
