Just posted my last remaining 22,500. So that is 50,000 from 1 personal and 1 business opened mid December 2009. 25,000 for a personal opened January 2010 and 25,000 for a business opened April 2010. 100,000 since mid December. All 4 accounts are still open. I'll close 3 accounts tomorrow now that 6 months are past and ALL of my miles are secure but I'll keep the one business since I've already picked up another 40,000 miles on 5 miles per dollar spent on Dell Business for IT purchases for my employer that are expensed and reimbursed.
