What disrupts MIA
American's gateway to Latin America runs enormous international banks, and summer brings near-daily afternoon thunderstorms plus the long tail of hurricane season. Customs and gate availability add friction international travelers should budget for.
Local knowledge: June–November, watch the tropics: Miami reshuffles schedules days before a storm arrives, and early rebooking is free.
