I searched but could not find anything, though I'm sure a thread exists.

How long does it take CO to mail you an ETC. My father was set to fly up to IAH on Monday morning back in July (7/14) but the flight was overbooked (F and Y, he was in F--airfcraft substitution) and they asked him to move to an Express flight the previous day (7/13) for $250. He did this but it is now 08/10 and nothing has come in the mail. How much longer should I wait before I e-mail We Care?
