Does anyone know if this also requires flying in PE? Could you book PE and then later upfare to Business?
I think the booked ticket is leading as upgrading to Business is considered a “seat selection”. Since the cashback is processed at AmEx’ end I don’t think KLM even communicates back what happens after - except cancellations
