Ticket Change and Exchange Rate Movements
I called BA around 6 weeks ago to change a ticket from Y to J. The fare difference was around £1,400 and the change fee £144.
At the time of the call, the exchange rate to the Australian Dollar was around 1.86. I considered this a fairly attractive exchange rate so gave my AUD card details instead of my GBP card details.
BA have only just charged my card, around 5 weeks later, and the exchange rate is now materially different at 2.03. This has resulted in the changes costing, for the two of us, $524.96 more than at the time I called and provided my card details.
Not wanting to get into a debate about exchange rate risk and the lag between authorising the amount and providing card details vs. the money actually being taken, what is BA's likely response if I ask them to reverse off my AUD card and charge to a GBP version?
I've flown the outbound but not the inbound. The original itinerary was updated on the 15th April, and card charged 20th May.
