This 'slump' in the airline industry will disappear almost as fast as it arrived. The gauge is not PPRuNe but the oil markets. Airlines are the biggest consumers of oil in the world and the collapse in the price of oil last year was a result of the collapse of the aviation sector. The introduction of a vaccine has changed the scenery completely and the price of oil, rising from $47 barrel to $67 in six weeks demonstrates that the aviation industry is going to take off again.
It will not happen this year but by the end of next year this whole thing may well be a memory.
Go for it.
