Well, guys, I just a got a replacement for my Delta debit card and I am afraid, I have a bad news. Because, after July 25, this card will become useless (for many people, at least).

Major changes:

1) Delta SkyMiles World card is available with a Signature Advantage checking account (info: $25 monthly fee, requires $25K to waive a fee).
2) If your balance is less than $100K - AF is $75, if more - $25. If you don't have a Signature Advantage checking account (like many here) - AF is $95.
3) Major change - MONTHLY MILES EARNING CAP - 4000 SkyMiles for Signature Advantage accounts, 2000 SkyMiles - for other checking accounts. Month means 30 day period.

4) Earning miles - 1 mile for $1 for Signature Advantage accounts, 1 mile for $2 - for others.

So, you have it. It seems that last avenue is closing. Very very sad year.
