Ryanair has further extended its connecting flights service to selected routes at Porto airport.

The low-cost carrier launched the service last summer at Rome Fiumicino, before extending it to Milan Bergamo, and has now added an initial 20 routes through Porto.

These include from Madrid to Lisbon via Porto, and from Barcelona to Faro, Lisbon, Ponta Delgada and Terceira.

The service allows customers to check-in luggage through to their final destination, with one booking reference for both flights, and avoids travelllers having to go landside at Porto when connecting.
