Most airline reservation systems require a saved booking (PNR = Passenger Name Record) before they can issue a ticket. So, the booking class and seats are locked in before you can make a payment. Once that's done, they can't really change the price, and you can pick which card you use. So, I would suspect that they aren't trying to identify a corporate card as part of their segmentation strategy.
