I redeem award miles for airline trips a couple times a year with various USA airlines.  Today I learned about of some USAirways charges that are way beyond what any other USA flag carrier imposes. \n\nA month ago I booked a Dividend Rewards mile redemption flight for a friend on Virgin Atlantic from London Heathrow to Boston Logan.  Today, I requested different flight dates, from March 3/9 to Feb 21/28, keeping the exact same itinerary.  Then, I am told that there is a $250 charge for this!  According to USAirways site (since checked), it doesn't matter that the flight is on a partner airline.  That is what they charge for ANY transatlantic flight change!\n\nI have never experienced anything like this. For example, AA charges $0 for this type minor change.  I know and expect stricter rules and fees but this seems off-the-chart and much worse than USAirways' competition.  So much so, I hadn't bothered to check this prior to booking.  \n\nFor a couple of years I was a preferred status flyer with these folks.  That will never reoccur.
