Porto Airport liquid rules — FAQs (2026)

What are the liquid restrictions at Porto Airport in 2026?

Porto recommends 100ml containers in one transparent bag of up to 1 litre, presented separately. Some checkpoints allow up to 2 litres without a bag, but the airport says you can't predict which checkpoint you'll use.

Does Porto Airport have a 100ml liquid rule?

The airport recommends packing to it. Some checkpoints allow larger liquids, but there's no way to know in advance which one you'll go through.

Can I take bottles over 100ml through Porto Airport security?

Only if you're screened at a checkpoint with the new equipment — which you can't predict. To be safe, decant into 100ml bottles or pack larger ones in checked baggage.

Are there any Porto Airport liquid restrictions on duty-free?

Keep duty-free liquids sealed in the shop's tamper-evident bag with the receipt. If you connect through another airport, ask your airline about that airport's rules.
