This situation does not appear to have improved with passengers telling The Portugal News that “massive queues” at passport control continue at the airport this morning.

A report from the Daily Mail alleges staff shortages and “lack of information from airlines”.

A report from CM stated that police put the disruptions down to a “peak in passenger arrivals”.

“The PSP had all available staff working, with all document control booths open. But it took a while to let passengers on flights that arrived in the morning”, said the police source.
