I just redeemed a Business Class ticket LHR-YVR-PHX-SAN (AC/US) returning SAN-IAH-LHR (CO) and it was processed by the end of the day electronically. It took longer than the 3 hours, but all were confirmed in I and O classes respectively and the taxes already charged to my CC within 24 hours. Was great to find availability at 105K in August, where even economy fares are high!
