✈️ Flight Guide: Chicago (ORD) → Boston (BOS)

Key October events affecting ORD to BOS travel include Boston's Head Of The Charles Regatta (late October), Halloween and historic ghost tours, and New England fall foliage season that draws leaf-peepers from Chicago O'Hare International Airport (ORD).

These events can increase demand for flights, hotels, and car rentals — reserve early and consider midweek travel for better pricing and availability.
