A few years ago US airlines started charging really big passengers for 2 seats. Well I just heard that in Canada they passed a law that states, large passengers have the right to 2 seats if needed, but can only be charged for 1. I hope I will never be in that position, but it's good to know.
Also, when crude oil was at $147 a barrel, airlines started charging for baggage. I have not heard that this has been stopped now that crude is $47 a barrel.
