Fortunately as a passenger the economy flight area was very spacious due to low numbers of passengers. Which provided a comfortable seating space.

The entertainment could and been a little more variable in the film range provided. But generally overall I had a excellent flight. Food was good. Crew were very good and I would definitely consider flying United on my next visit out and recommend that my family did. Thank you United.

Our plane was defective so had to be replaced. This is fine, I certainly am willing to wait for a new plane if it means not blowing up over the ocean. The problem was how little the attendants at the gate communicated the situation to us. What should have been a brief layover became a 12 hour nightmare. The gate attendants did finally issue meal vouchers but they waited until 10 minutes before all the restaurants closed and only issued $10 a person. This is enough to buy a hot dog at an airport... We were told there wouldn't be any rescheduling of missed connections until we were "airborne". This resulted in mass panic and confusion upon reaching our destination. We were told to go to the service desk, half an airport away, but once the entire passenger contents of the plane arrived at that far flung service desk, we were mostly turned away to seek help at individual gates. This lack of communication meant I missed the next next available connecting flight and now have a further six hour layover. I understand accidents happen and planes can break down but the nearly complete lack of care and customer attention is, frankly, disappointing. I've now had nearly an entire day added to my travel time. If I'd been willing to loose that time I would have paid $600 less for my ticket. United finally offered a token of their appreciation : a $100 e-voucher. I have spent more than that on food and coffee in airports for the past two days while trying to survive until my next connections.

Its a scam! They act like they are giving you a break by having you buy cheap flights but in reality it costs more than a bit more expensive flight. I had to pay $45.00 each bag no matter if it was checked or carry-on. In total round trip I paid $180.00 extra just for my husbands carry-on as well as mine. Must add that our flights together cost 286.00. We should of went with American Airlines. On top of that we couldn't select our own seat if so, we had to pay extra, so we had to sit separated from each other. It was ridiculous! Never Again with this company!!!!!

*
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.
