Changes to Award Ticket (Dates)
I've got a few award tickets that I basically booked just to empty my MM account and, amongst those, there's a MAN-AMS-DTW that I'm due to fly next week: I originally booked it back in March and had to tweak it slightly in terms of dates roughly a month ago. Does anybody know how many changes [in terms of dates] are allowed without incurring in penalties?
Cheers,
G
