The above got me thinking about soon-to-expire jokers.

It's possible to use a joker in "this" year for a trip which takes place "next" year. By 'year', I'm referring to the tier point collection year.

But once you're in "next" year, what if you want to modify the dates. Does that still count as the joker from what will be the previous year, or will BA insist you use another joker in the new, current year.

If a joker is about to expire, and I know I want to travel to a destination, but don't know the exact dates, can I use a joker for the rough dates, and then tweak them closer to the time under that same joker.
