We wouldn't travel in June, July or August, and not in Jan, Feb or March. We would choose either April or September.
April - banking window is Nov 30th, so if we book in Dec, we would still cancel 31 days out, so still within banking window.
Sept - banking window is April 30th, so if we book May, we would still cancel 31 days out, so still within banking window.
Unfotunately, these are the 2 least plentiful UY around, but with both as an option, it double our chances of finding a perfect contract (our 1st.)
