Just wondering as I read hersheys TWA post on alterations for award tickets if anyone has any scientific or anecdotal info on differences in ease or difficulties returning e-tickets for refund compared to paper? You have the receipt and I guess they would just check to be sure you did not go on the flight? presumably you may also have a boarding pass but might have given it up and deplaned after a mechanical or ATC or something!

Also, on the mileage credit front, any differeences observed here with either accuracy or promptness of miles posting on various carriers. Most of my etickets have been freebie award travel and I never relly thought about this before!
