Tips for International Travelers

When traveling internationally, online check-in can be particularly beneficial as it helps you manage your travel documents and other requirements proactively. Ensure you have all necessary documents ready before you check in to avoid any last-minute hassles.

  • For U.S. citizens, ensure your passport is valid for at least six months beyond your travel dates, as some countries require this.
  • Check specific entry requirements for your destination, especially for countries like Canada, the UK, UAE, Australia, and various European countries, as they may require additional documentation.
  • Familiarize yourself with customs regulations of your destination to avoid bringing prohibited items.
