Flights are booked

My flight is confirmed for September 11, yes I know a very notorious date, however I figure maybe the flight will be quieter if people are suspicious of flying on that date. This makes no difference to me.
I leave Toronto at 1:40am which means I am to arrive at the airport at 11:00pm on September 10th.
Stay with me now, then after 15hours of non-stop flying I arrive in Hong Kong at 6;30am on the 12th.

After a 12 hour stop-over I leave for Kathmandu at 6;30pm, quick stop in Bangladesh and finally arriving in Kathmandu at 10:30pm. I will be met at the airport by a representative of the organization and driven to their house where I will sleep for a long time!
