I have 700$ stuck on AA due to a cancelled booking that I have to use (book) before July. Any ideas on what I shall do?

I must depart from Spain. I can add money of course.
Any ideas arre much welcome!
Can't seem to find any good prices in Business at this point either.

Must be bookable at AA.com

Prices seem to have risen departing Spain. I wish I could get the same prices that are offered from Scandinavia at this point...
