International airfares are generally the lowest during the summer months of July through August. But, it’s not unheard of to find some bargains in this period. January is also a good time to purchase international tickets as prices drop due to fewer travelers using the system at that time. We recommend buying your tickets 60 days prior (for Europe, Asia and Central America) or 90 days prior (for most other regions). Most airlines will allow you to change or cancel your ticket without penalty up until 48 hours before departure date; however, there is no guarantee they will honor these changes if they enter their reservation system after this point.
