Route Tips
- Athens Airport (ATH) is relatively small and efficient—arrive 2 hours before flights. Terminal A handles non-Schengen flights including Lisbon routes. Security can be busy during morning peaks (7:00-9:00).
- Portuguese immigration is straightforward for EU citizens using the eGate system. Non-EU travelers should ensure 90-day Schengen limits are not exceeded before arrival.
- Consider a Lisbon city break in shoulder seasons—the weather remains mild (15-22°C) even in November, and hotel prices drop 30-40% compared to summer.
- For baggage on connecting flights, note that unless booked on the same ticket, you may need to collect and re-check bags during layovers. Book single tickets for better protection.
- Ryanair occasionally operates seasonal Athens-Lisbon routes via their European hubs—check their website monthly for sales, but be prepared for basic conditions and strict bag policies.
