A record 38.9 million passengers used Portugal's airports last year, an upturn of 11% on 2014, the bulk of which were handled at the nation's three biggest gateways – Lisbon (20m), Porto (8.1m) and Faro (2.7m).
Another 2.7 million passengers passed through Madeira and 1.6 million in the Azores.
Lisbon's success continues to impress, the 10.7% rise in traffic throughput in 2015 meaning that passenger numbers have soared by 4.8 million in the last three years and by 4.6 milion in the previous eight years.
Last year's traffic rises at Porto and Faro airports amounted to annual upturns of 16.7% and 6.4% respectively.
ANA attributes the healthy rise in traffic to "the attractiveness" of its airports network, its route development efforts – which last year led to the launch of 20 new services – and the growth of low-cost carriers.
