  • Avoid the Labor Day surge: If travelling to the US, steer clear of the first Monday in September, and plan your trip after that date for lower fares and fewer crowds.
  • Consider layover options: For long‑haul routes to Europe or Asia, compare direct and connecting flights; a stopover can still offer significant savings in September.
  • Review luggage policies: Weather can vary widely, from warm Mediterranean afternoons to chilly mountain nights in US parks, so check baggage allowances for layered clothing and outdoor gear.
