So I am GGL and am planning to use a joker for a flight for 5 for next summer. I have previously used both my 2 for 1 Amex voucher as well as my wife’s 2 for 1 Amex voucher when doing a joker booking, I presume this is still available (and still can combine with GUFs too?). And secondly I currently only have one 2 for 1voucher but will have passed the 10k spending threshold for the other in the fourth quarter. I presume it would be possible to book the whole trip with just one 2 for 1 voucher now and then amend the booking later to add the other 2 for 1 voucher when I have qualified given it’s free to cancel as a GGL and clearly the 5 seats should still be available as they would have been mine anyway.

let me know if any issues with my plan before I go ahead!
