My Capital One credit card just sent me 3 checks with some pretty favorable terms. There is no fee at all, they post as purchases instead of cash advances, and are not restricted to balance transfers. (Sadly, they don't earn C1 rewards). SO I was thinking I would write myself a check for close to my $20K credit limit and deposit in into BankDirect right after my monthly C1 bill closes. That gives me 7 weeks until I have to pay the C1 bill, so 7 weeks of earning AA miles from BD. On $20K, that's about 3500 miles. But how long will BD take to clear the check? Folks over on FT are saying it could take weeks(!); if it's going to be a month, and if I don't accrue miles until it clears, then this becomes much less worthwhile. Does anyone here have experience with large check deposits at BD? Would it help to split the deposit up across multiple checks (C1 sent me three of 'em)?
