I want to redeem points for a coach seat and pay cash for a business-class upgrade. Can that all be done as one transaction? If so, by which means: phone/online/station agent? Does it require two transactions? Say, book coach online, then later modify the transaction to upgrade to business class?
If it can't be done, is there a Plan B I can use?
