waiting 3 hours at the airport between flights is nothing
bring a book!
Not when you have over 3 hours flights before and after
The late flight will arrive Calgary near midnight and my brother, the one who will pick me up, has to work early in the morning. So I try not to inconvenience him too much.
I am trying to not have check-in luggage this time so carrying a book will be too much but I can have electronic books loaded into my ipad
