For domestic flights, it is generally recommended to arrive at the airport about 1.5 to 2 hours before departure. This allows enough time for check-in, security screening, and reaching the gate without stress. If you only have hand luggage and have checked in online, arriving about 1 hour early may be sufficient in normal conditions. For international flights, arriving at least 2 to 3 hours before departure is advised. This extra time accounts for passport control, visa checks, and additional security measures that vary by destination. For flights within the EU, 2 hours is usually enough, but for international flights outside the EU, 3 hours is safer. In summary:

Flight Type| Recommended Arrival Time Before Departure
---|---
Domestic| 1.5 to 2 hours
Domestic (hand luggage, online checked-in)| About 1 hour
International (within EU)| About 2 hours
International (outside EU)| 2 to 3 hours

These guidelines ensure enough time for check-in, security, boarding, and possible delays.
