How many hours before an international flight should travelers arrive at the airport to avoid issues?

Travelers should aim to arrive at the airport 2-3 hours before an international flight to ensure a smooth travel experience. This timeframe allows sufficient time for check-in, security screening, and potential delays that could arise during the boarding process. International travel typically involves a variety of steps, including passport control and customs clearance, which can take longer than domestic travel.

Arriving within this window helps mitigate stress and gives passengers the chance to address any unforeseen issues, such as long lines or missed necessary documentation. The specific time range of 2-3 hours is widely recommended by airlines and travel experts, as it balances safety and convenience for most travelers embarking on international flights.
