Just wondering if anyone has upgraded their Barclaycard Rewards Mastercard to a World version? If it's even possible?
BarclayCard - Rewards MC - 5,000 | Amex - Skymiles Platinum - 18,000 | Chase - Freedom - 3,000 | Chase - Hyatt - 5,000 | Amazon SC - 3,800 | Fidelity AMEX - 17,000 | Chase - Ritz - 10,000
