Let say if BA increase the avios required for the route, or if the taxes increase, will I need to pay the difference? Conversely, if any of these elements decrease (unlikely, I know) will the difference be refunded?
Also, if I were to use the voucher to book a flight on a different route with cheaper avios and/or taxes requirements (e.g. a short-haul in Europe), what would happen to the remaining, unused, avios and cash on the voucher?
Yes, a Future Travel Voucher could lead to a fare difference increase or decrease. An increase means you have to stump up more Avios and/or cash. A decrease will be remitted back to you via a refund of Avios and / or another eVoucher. If you rebook instead of FTV for the same route then you won't get a fare difference issue. You can book to another route, the FTV is not route specific, or for BA Holidays, though for a 2-4-1 that isn't typically a good idea.
