Lissabon flygplatsens webbplats rekommenderar att du, även om du har checkat in online eller har boardingkortet, ska återvända till flygplatsen inte mindre än 90 minuter före din vidare flygning (även om anläggningen har en storlek och layout, ska 75 minuter vara tillräcklig).
Det föreslår till och med ett besök i stadens centrum under en lång layover, och erbjuder att hålla fast vid vilket bagage som helst.
How far in advance do I need to check-in?
The recommended check-in time varies depending on the flight. In order to avoid delays and make the most of your pre-boarding time, please respect your airline's minimum check-in time. That way, you also avoid the risk of arriving after check-in closes:
At the Airport's check-in desk:
- Schengen flights: 90 minutes
Schengen regulations have removed controls at the internal borders of signatory states: Germany, Austria, Belgium, Denmark, Slovakia, Slovenia, Spain, Estonia, Finland, France, Greece, Holland, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Malta, Norway, Poland, Portugal, Czech Republic, Sweden, Switzerland.
- Non-Schengen flights (Europe): 120 minutes
- Flights to Third Countries (Intercontinental): 180 minutes
For most airlines, check-in can be made online 48 hours prior to boarding – check the recommended check-in time with your airline in advance.
Flights to the United States and Switzerland - 24 hours
Remember that, after checking-in, you will have to go through X-ray screening and, when travelling to non-Schengen destinations, you must also go through passport control. Therefore, avoid delays and plan your arrival at the airport in advance.
