Mediocre 2.6

Cons: The price was good, before you realized the price was a lie and they scam you by charging $45 to carry on or $40 to check a bag! That meant the overhead space was unused and they were just charging more just to be inconvenient. The plane was stripped barebones. The crew were rude, did not smile, and gave me attitude for hitting my elbow with the drink cart. They charge for even getting a soft drink. Nothing about the experience said "we're serving you." It's worse flying a more expensive airline because the rediculous bag fees make it just as expensive and even things that should be free like pleasant staff were lacking.

ORD
SFO
Mediocre 2.6

Pros: Price

Cons: Very rude staff. The staff on the plane were ok but the staff at the ticket counter were very rude. I also had a similar experience when I flew to Vegas. I don't care how cheap the prices are, frontier needs to get there act together. There are a lot of other companies to fly with.

Pros: I was impressed with the pilot. Had a very smooth flight. Was one of the best I have had flying.

Cons: I had a window seat and was very cold. Crew did not go out of there way to make you feel like they cared. A "hello" and "goodbye" was the most we received. The seats could be more comfortable and roomy. Also, when we we arrived the jet bridge did not hook up properly and not one of the crew said to be careful when leaving. It was a good thing I payed attention because it was at least a 3-4 inch drop.

Pros: Crew was attentive.

Cons: From Gregory at the check in being rude and anything but welcoming, to seats in first class needing replaced, this was anything BUT a first class trip. This was my second time giving United a chance as I normally fly Delta. I don't think I'll make that mistake again. I understand a late night flight doesn't have a meal service, but snacks of chips and bananas is not my idea of how you should serve Firat Class passengers. I would have a hard time recommending anyone choose United as their airline. Time for an upgrade of not just the seats, but overall customer service.

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.
