I have a ton of miles on Usair and was wondering when they release the dates for booking? In otherwords, does anyone know if it is a set amount of days and 12:00 midnight eastern when you can pop for a destination on-line in order to utilize least amount of miles for First class? Does it depend on detination etc.? Would love to know so I can try and do the "midnight booking". most dates i am looking at next fall for Europe are already 100K mles each way to europe. Thanks!
