No airline charges to use the toilet, Ryanair only announced that they were considering it and have not begun charging to use the toilets. Many considered the announcement as nothing more than than a way to get free publicity.
I dont know about America but the only airline that i have heard who is considering charging for using the toilet is Ryanair who are a European no frills airline who will charge you for just about everything possible , possibly even for using the oxygen masks in the event of an emergency.
Only Ryanair, no other airlines charge to use the bathroom
I don't know of any airline that charges for that.
none yet !
