Flight on time and efficient

We arrived 2 hours early and checked our bags in with priority. Somehow, they still managed to get our bags stuck in Houston on a direct flight from Cancun to San Francisco. Makes absolutely no sense.

United terminal in San Fransisco is pretty nice.

The service by flight attendants is horrible. They are not even pleasant to talk to. They are not helpful. My audio jack was not working and the flight attendant just replied. Nothing I can do. She didn't offer any solutions. The airplanes are like buses with amenities, no leg room even in the economy plus. Just a horrible experience, overall. I have flown multiple airlines but the United is by far the worst airline in terms of service, customer support and airplane quality.

Was told there was a delay of 15-30 mins at check in. Flight was actually delayed 1.5 hrs. Would have been nice if they explained why ahead of time.

More food options. Almost wasn't able to buy food. Was told they ran out by the time they reached us in the back of the plane. Luckily they had one left. It was luke warm at best and my husband and I split it.

We missed a connection due to it being an international flight with several checkpoints of customs and immigration. No one from United seemed to care that we missed the connection. We won't fly United again.

Flight was short

Flight's departure time was delayed by an hour an 10 mins. Apparently, due to a long plane queue for take off

Space is very important to me and there was great leg room. For the most part the stewardess were great but sometimes a little tricky to find. They did offer complimentary alcohol which was nice.

It was a major bummer on a 5 hour flight that there was no entertainment and no wifi. Also we didn't know the seat assignment until we checked in. Once on the plane it was clearly not a full flight but they still had everyone crammed together 3 to a row.

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.
