Can I just say, Lisbon airport is the worst airport in the world I've ever visited... I flew from Amsterdam to Ponta Delgada in 2019, with a connection in Lisbon on the way there and in Porto on the way back, and the contrast between the run-down, comically undersized Lisbon Airport and the modern, clean and intuitively navigable Porto Airport is énormous. I hope Lisbon gets a major overhaul of its airport soon, because it deserves better...
