Pack in layers: bring cold-weather outerwear for Buffalo Niagara International Airport (BUF) departures and lighter layers plus sunscreen for Orlando arrivals. January travelers should prepare for winter driving to BUF, clear snow from vehicles, and arrive early for check-in due to potential de-icing delays. For Orlando, bring a light jacket for cooler evenings and comfortable walking shoes for theme parks. Always have digital copies of travel documents, set fare and flight alerts, and consider travel insurance or refundable tickets if traveling around MLK weekend or major events.
