The flight was comfortable with the exit row and great service

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Ok. Get a different kosher caterer. The food was odd.

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

1.It will be better if sandwich is warm. 2.The food is too salty. 3.Breakfast needs some vegetables or fruits.

Boarded plane and then delayed 1.5 hours while on the plane

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth
