Always plan this way in advance. Now there is 1 holiday month left......Sure, you can do the runs as suggested and buy SAF to the max (you have good old Saudia Tunis-Asia in J which often is 1000 Euro, but do not know so short in advance they still have this) and you may be able to get 240 XP for say 3k. If you have a stack of miles, you can also give to charity gaining 1 XP for 2000 miles or so.
