Cheap

As usual, Frontier charges for everything extra. Also, their seats don't recline, which is ok for a short flight like this one from Austin to Reno (CA. 3 hours.)

Excellent 8.0

Practicality, assigned seats, non-reclining seats, clear "extras" policies and prices

Onboard crew friendly. Plane was clean and new

Chaos during boarding. Sat on ramp at Denver for a long time waiting for a gate to deplane.

Nothing at all

Instead of letting me carry my skateboard with me they Made me check in my skateboard, pay for it as a separate carry on, then lost it. Told me they would refund me the carry on fee and still haven’t. They also haven’t tried to contact me about my missing item. Terrible

These people have no idea who or what United Airlines is. They work for Delta, and make sure they tell everyone about it.

See above. The flight itself was fantastic. Larger planes are the best! Thank you!

The personal entertainment is always great on United

This was a comedy of errors of United being terrible at their own airport. The first plane essentially had a check engine light that they couldn’t figure out. Finally got us a second plane but then got delayed because they couldn’t get catering to come service the plane. The food on the plane looked like it has sat outside for hours. The oils in the hummus and bruschetta has seperated. Good try United but if you can’t get it right at your base how do you expect to get it right anywhere else.

The United stewardess was lovely

The women in the Redmond/Bend security were less than friendly and helpful. In fact she seemed intent on delaying us for no apparent reason.

Arrived on time, even after delayed departure

1 hour into the flight until the internet worked. Crashed 2 hours prior to landing. Horrible to fly cross country with no internet.

Flight was on time and we arrived earlier than scheduled time

I only had an hour to catch this flight because my flight from Vienna to Chicago was half hour late to park at the gate, and was scrambling in the busy O'Hare airport to go through passport check, customs, catching the train to go from Terminal 5 to 2, passing through security (YET AGAIN!!!) and running to my gate They didn't even offer some water Took longer than usual to get our luggage

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,
