Maximize space by packing mini toiletries, wearing your bulkiest attire, and organizing outfits strategically. This approach also lets you avoid waiting at baggage claim upon arrival.
Bring your own entertainment—many short-haul flights may not provide in-flight entertainment. Download TV shows, movies, music, or podcasts ahead of time and consider bringing a book to keep yourself entertained. Remember to fully charge your devices before you board.
Arrive at the airport in plenty of time—even 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 security lines.
Bring your own snacks and water—pack snacks and a refillable water bottle to stay hydrated and save money while at the airport.

Select your seat in advance—for longer flights, choosing your seat is crucial for comfort. Full-service airlines often allow you to select seats for free once online check-in opens, typically 24–48 hours before your flight. Some airlines may permit seat selection even earlier than this.
Arrive at the airport in plenty of time—aim to arrive at the airport at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration procedures.
Relax at the airport—if you find yourself with extra time, take a moment to 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 readily available.
Adjust to the new time zone mid-flight—begin syncing your body clock by changing your watch and sleep schedule to align with your destination's time zone. Try to sleep or stay awake on the flight according to the local time at your arrival destination to help minimize jet lag.
