These travel windows align with lower demand periods in the North America to Southeast Asia corridor, which means premium cabin inventory is more accessible and private fares tend to be significantly more competitive. Booking 60 to 90 days in advance during these windows gives your Personal Travel Manager the best leverage when sourcing unpublished rates.
