I apologise, as I can't be the first person to raise this question, however due to a couple of flights being cancelled (and subsequently rebooked) within the 24 hour BA cancellation window, the cumulative spend on my card must have passed the £10k threshold for a marginal period of time.

This in turn triggered the voucher (which to be honest, I didn't want to happen yet)

If I log in to BA, the voucher is there

If I log in to American Express, it says I need to spend another £1k

Will this situation automatically resolve itself? If not, is it hassle to correct?
