I have noticed that when flights originate in the USA (With both Delta and United) that the initial baggage charge is $USD25. But when taking flights from Canada back to the USA the baggage fee is $CA25.
Is there any explanation for the difference in baggage fees other than "because"?
Currently $USD25 is $CA33 and $CA25 is $USD19, so there is a significant price difference that has nothing to do with exchange rates. (And 2 weeks ago when I did the same trip the exchange rate was even worse and the equivalent CA->USA price was $USD18)
