  • Pack light and skip checked bags—when flying with budget airlines, traveling with just a carry-on is often more cost-effective. Maximize space by using travel-sized toiletries, wearing your heaviest clothing, and coordinating your outfits. This approach also helps you avoid waiting at baggage claim upon arrival.
  • Bring your own entertainment—many short-haul flights may lack in-flight entertainment options. To keep yourself engaged, download TV shows, movies, music, or podcasts ahead of time, and consider bringing a book. Remember to fully charge your devices before you board.
  • Arrive at the airport in plenty of time—for both short and domestic flights, it’s advisable to arrive at least 1.5 to 2 hours before departure, taking into account traffic and 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.

  • Arrive at the airport in plenty of time—make sure to reach the airport at least 3 hours before departure for international flights to accommodate check-in, security, and immigration processes.
  • Relax at the airport—if you have some extra time, explore the shops, grab a coffee, or unwind at the gate or in a departure lounge if you have access. Airport Wi-Fi is generally free and available.
  • Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and modifying your sleep schedule to align with your destination's time zone.
