Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

Flight and crew were great. United didn't inform crew of immigration process which was disappointing!

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Friendly and professional flight crew. Aside from departure delay after boarding, easy flight and smooth landing.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

Boarding was organized. Old plane. Seat fairly comfortable. Business Class much too large so you don’t receive as much attention as you should considering what you pay for the seat.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

The food should improve! And The flight should leave on time and not make the traveler wait.
