This poster in the BA lounge reminded me that there was a time when flying boats were thought to be future of commercial aviation. Before the World Wars, when there were still few airports and appropriate infrastructure around, landing on water was considered the most efficient way of getting people to their destination. However, German air raids necessitated rapid development of airfields for defence purposes that turned into some of the busiest airports in the world today. After the war, airlines stopped buying the flying boats as planes landing on tarmac were considerably cheaper to maintain. A black swan like COVID-19 may bring about similar change. Will airlines scrap their older B747s and A380 quad-jets as demand dries up? Probably. It has already happened at KLM and Qantas. BA may be next and it's no secret that Air France is getting rid of their A380s.
