To secure cheap flights from Boston Logan International Airport (BOS) to Port Vila Bauerfield International Airport (VLI) in October, start by searching flexible dates and setting fare alerts that include nearby hubs (e.g., BOS→NAN→VLI). Consider splitting tickets and comparing one-way segments: Boston to Nadi or Sydney on major carriers, then Nadi to Port Vila on regional airlines. Use mid-week departures, avoid major U.S. holiday weekends, and price-check multi-city itineraries. Primary keywords: “cheap flights Boston to Port Vila October,” “BOS to VLI deals.” Secondary and LSI keywords like “shoulder season Vanuatu fares,” “Boston to Vanuatu via Nadi,” and “discount Pacific island flights” should be included in searches and fare-watch alerts. Book once a good fare appears — fares can rise closer to October when seats are limited on regional legs.
