I arrived - finally (though stuck on the runway at SFO as I write this)

Crowded, chaotic boarding area & process at Boston Logan. Checked in seats manually since systems apparently down. An hour delayed (on takeoff) for no apparent reason and delayed waiting for gate on arrival. Seems to happen regularly with Alaska but not JetBlue Broken restroom - should have at the very least let coach customers use First Class restroom rather than get by with one Broken wifi - none the entire flight Limited food which ran out quickly Flight attendants trying but seem harried and confused and not very attentive

In-flight entertainment was excellent: many options including in-flight wifi.

I think it is time for US airline companies to provide complementary meals in their long flights. A 6 hours flight with just a small bag of chips? European airlines offer a complementary full meal even with a 2-hour flight...

I told attendant my carry on had Med equipment. She proceeded to stow other larger carryons and tried to get me to check it — then she just put it in biz class. Cabin was hot. They brought me just after takeoff instas of at lunch time. My entertainment system didn’t work and the only response was “we’re aware of it” no attempt to fix, no apology. Then flight attendant skipped my tow with drinks.

A very tall, male, flight attendant very wonderfully took me almost all the way from one end of the horseshoe to the other. I didn't catch his name but he was SO helpful.

My flight was delayed by a few minutes and by the time we got to San Francisco, boarding was almost done for my connecting flight. I had to literally run from one end of the United terminals to the other... the entire horse shoe.

the boarding process is horrible and feels rude. The design of the united gates is horrible, the long lines block others walking by. The lack of enough overhead space for carryon's is obnoxious. Overall very disappointing.

For an extremely late gate arrival, United personnel were very accommodating.

One flight attendant was more than curt and impatient when taking food orders. Cabin announcement told passengers to check menu in setback pocket. There was no menu. Attendant didn't offer one until another passenger who overheard conversation requested menu. As a frequent United traveler BOS > SFO, normally a 5-6 hour flight, attendants always seem to be rushing, brusque.

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,
