Tips for short-haul flights to Glen Carbon

Bring your own entertainment—many short-haul flights do not provide in-flight entertainment options. Prepare by downloading TV shows, movies, music, or podcasts ahead of time, and consider bringing a book to keep yourself engaged. 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 prior to departure, taking into account traffic and security lines.
Bring your own snacks and water—pack your favorite snacks and a refillable water bottle to stay hydrated and save money at the airport.

Arrive at the airport in plenty of time—plan to be at the airport at least 3 hours prior to departure for international flights, allowing ample time for check-in, security, and immigration procedures.
Relax at the airport—if you find yourself with extra time, take the opportunity to browse the shops, grab a coffee, or unwind at the gate or in a departure lounge, if accessible. Airport Wi-Fi is usually free and readily available.
