  • Pack light and skip checked bags—when flying with budget airlines, traveling with just a carry-on can often be more economical. Maximize your packing by using mini toiletries, wearing your bulkiest clothing, and carefully planning your outfits. This strategy also helps you avoid the hassle of waiting at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights may not provide in-flight entertainment options. To keep yourself entertained, download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book. Be sure to charge your devices fully before you board.
  • Arrive at the airport in plenty of time—for short or domestic flights, it’s advisable to arrive at least 1.5 to 2 hours prior to departure, taking into account traffic and potential security lines.
  • Bring your own snacks and water—pack some snacks and a refillable water bottle to stay hydrated and save money while at the airport.

Some airlines may offer seat selection even earlier than this.
  • Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours before departure for international flights to accommodate check-in, security clearance, and immigration procedures.
  • Relax at the airport—if you have some extra time, take the opportunity to explore the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Most airports provide free and accessible Wi-Fi.
