It doesn't seem bad, except the cost of issuing an e-ticket 2 days in advance isn't any higher than 100 days in advance. In fact, the cost of the reard ticket 2 days in advance is probably less, because it's much less likely to change.

I'm all for people paying more for convenience on a revenue ticket. On a reward ticket, if it doesn't cost the airline any more money, it shouldn't cost me any more money.
