• Pack light and skip checked bags—when flying with budget airlines, it's often more economical to travel with just a carry-on. Maximize your space by using travel-sized toiletries, wearing your heaviest clothing, and coordinating your outfits in advance. This approach also allows you to bypass the baggage claim once you arrive.
• Bring your own entertainment—many short-haul flights might not provide 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—even for short or domestic flights, it's advisable to arrive at least 1.5 to 2 hours prior to departure, taking into account potential traffic and security lines.
• Bring your own snacks and water—pack some snacks and a reusable water bottle to stay hydrated and save money at the airport.

Some airlines even provide seat selection earlier than this.
• Arrive at the airport in plenty of time—make sure to reach the airport at least 3 hours prior to departure for international flights to allow sufficient time for check-in, security, and immigration procedures.
• Relax at the airport—if you have some 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 usually free and readily available.
