October travel from Hartsfield-Jackson Atlanta International Airport (ATL) to Kahului Airport (OGG) benefits from shoulder-season advantages: lower hotel rates, fewer crowds, and generally great beach weather. Still, October is within the Pacific hurricane season—so check forecasts within 7–10 days of travel, consider refundable fares or travel insurance, and register for airline flight alerts. Pack reef-safe sunscreen, light rain layers, and comfortable hiking shoes for Upcountry excursions. At ATL, arrive 2–3 hours early and use expedited security options to minimize stress. At OGG, expect moderate lines at rental car counters—reserve vehicles in advance and confirm pick-up times.
