With just one terminal building at Robin Hood Airport (DSA), the chances you'll lose your way are very slim. Check the airport's official website to discover what services and facilities are on offer in the departures lounge. Avoid the mad dash to your departure gate, or missing your flight completely, by arriving 1.5-2 hours prior to domestic flights. Aim to arrive 2-3 hours beforehand if you're flying internationally. This will allow you time to drop off bags, clear customs and security and make your way to your gate. To get the most accurate advice, check the arrival time recommendations of both your departure airport and airline.
