I seem to recall a recommended wait time but can't remember how long. I finally got around to selecting airline as DL on my plat tonight about 7 PM. Would like to get 4x$50 DL GCs pronto (esp b/c it takes 48 hours for them to activate...WTH?). Amex site says it is instant (in terms of DL as "selected"), and I did get an email confirmation, but I have a vague memory of reading somewhere that someone "selected" then went to DL for GC and the credit never posted. How long should I wait to get the GCs?
