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.

Plane was old and dirty, seat pocket had junk in it. Seat was broken and couldn’t stay up. In flight movies were from few years back with a center tv and no head rest screen. Crew on overseas flights tend to be older in age and less tolerant..much better on continental on the same route.

This flight was miserable. Seriously, one of the worst flight experiences I've ever had. The leg room was absurdly small. I'm not a tall person and I only had one inch in front of my legs. When the guy in front of me put his seat back it pressed into my knees. There wasn't enough space to bend down and untie my shoes, let alone get something out of my bag. My shoulder and knee were touching the guy next to me (a complete stranger) for the entire flight and there was nothing I could do about it. This was a red-eye but I absolutely could not sleep because it was so uncomfortable, so when we landed I had a terrible migraine and was nauseous and disoriented going through customs. I actually had to sit down in the airport because I though I was gonna pass out while trying to carry my bag, that's how shitty I felt after this flight. On top of that, not being able to sleep on the flight really messed up my sleep schedule and so jet lag from the time change has been made even worse, so I'm completely out of whack and its so much worse that it otherwise would have been because of the horrible flight. Also the food was gross and there wasn't enough of it. Even now, I don't think I have really communicated just how shitty this flight was. I was actually angry when I saw my seat upon boarding, and I'm still angry about it now.

The food is very tasty, but AA has not changed the menu in at least one year.

Smooth operation, on time

Seat pitch on the plane unbelievably cramped. When seats are so close that if you drop something on the floor you have to be a contortionist to get it, you know it's a problem NEVER fly the 787-900 economy.

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.

Flight delayed missed connecting flight. Second flight delayed missed connecting flight. Overnight in airport expected unless united pays for hotel. Absolutely miserable. Paid 430$ one way for a 25 hour flight. Will never fly United again.

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.
