So I applied for the MBNA Alaska card for the first time last week... did NOT get direct approval. Didn't call in. Today, the card came in the mail! And they extended the highest credit limit I have ever gotten to me without me even asking for anything - 60% higher than my second-highest card limit oO. What did I do to deserve this? Did you guys also get surprisingly high limits on the MBNA card? I mean I don't mind at all lol.

How long after the first purchase do the miles usually post?
