Pros: The crew made the best out of it and thankfully it’s an extremely short flight.

Cons: A 20 minute flight was delayed for 2.5 hrs. United did a terrible job with notifying passengers, just simply bumped out departure in 15 min increments. Original excuse was inbound delay, although plane was there for 6 hrs already. Passenger soiled himself in cabin and there was no ventilation.

Pros: Even though I was in Group C, I was one of the first to board (Groups A, B, and C were called to board all at once). Since the gate agent said the flight was full and there would be limited space for carry-on bags, being one of the first on the plane was nice. The leg room (I'm 6'2") was good.

Cons: The crew only did one pass through the cabin with soft drinks. Perhaps because it was a red-eye? Anyway, on a nearly 5 hour flight, I would have liked more than one small cup of refreshment.

Even in comfort+ class the seats are tiny with little legroom. Also, please clean the bathroom every few hours

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.
