Increased queues and waiting times at borders due to new controls introduced at Lisbon airport last week.
Passengers are reporting wait times exceeding four hours upon arrival in Portugal.
The new border control system aims for improved efficiency but has led to chaos for travellers.
Lisbon airport has faced challenges in implementing this stricter system which was meant to streamline the arrival process.
Thousands of passengers have been affected by the lengthy waiting hours, causing frustration and travel disruption.
