Flight was delayed over 8 hours due to "mechanical issues." Went from a nice 757 to a 737 which was a little more cramped.

Staff was friendly

United has a system glitch and we were delayed. I got in around 1 am instead of 11 pm. I decide to order a glass of wine and since they don’t give receipts. I found out i was charged for 2 glasses instead of one. To top it off the co-worker i was traveling with didn’t get charged due to the inconvenience and delay. i travel a lot with United (higher status than him) and would have liked that offer (and not get charged one i didn’t order) being a mileage plus and credit card holder. I did go on line and ask for a credit and they did make it right and give me a credit.

Good flight overall

The experience at DFW was terrible- long lines to get out of baggage claim because of too few agents to process 1000 people waiting. Also long lines for TSA screening to get to gate.

We arrived on time.

These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away.

Had xtra legroom and Wi-Fi

I paid the xtra $99 for the economy plus but my headphone jack didn’t work so I couldn’t watch a movie and my tray table was broken so I had to hold my drink and fumble with my food. The flight attendant tried to fix it but couldn’t. Made my 6 hour flight feel like 12 hours.

No baggage controls from seat 18 to 28 no bags would fit. As we exited all the front rows we're waiting to get there bags stored in back of planes overhead bins. That's just not right, especially when they charge us extra to take a bag for overhead bins storage.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
