Flight said canceled but they rerouted it to Oakland but no where on any monitors does it say this. The screen for boarding said Cancun even while boarding to Oakland. No one helping people when they got off the plane to transport them to SFO. Standing in the rain waiting for shuttle.Poor experience

I asked for a change of seat at the gate and was given it. It really made a difference to be at the window.

No crying babies and outlets at all seats.

I wish the seats reclined more or had more padding.

Excellent Crew - I flew standby, so have great gate agents and flight attendants makes all the difference when you’re hoping for a seat. In flight they are professional and personable and keep you up to date on what you need to know! Plus, I’m always happy when my flights have USB ports so I’m fully charged when I deplane.

I always want more leg room or a little more room under the seat in front of me. But I didn’t upgrade for a roomier seat and there was more than enough overhead space, so truly can’t complain about it!

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.
