OK. One question. How will wait-listing for I class work. Right now, you buy Saver (X class) and wait list for Business (I class) by having the mileage difference pre-deducted from your account. But if future I class awards have no fixed mileage price (until they are released, anyway), how can you pre-deduct the miles from a person's account? Further, what if when I class is released it is priced at a ridiculous number of miles. Will you have to pay it, or can you refuse it at that time. Or is the concept of a Saver award just going away?
