I think that in 20 years time, there will be precious few airlines left in Europe, and we will all be harking back to the "good old days" of the 2020s
Only a certifiable person would want to start an airline these days, the profit margins must be wafer thin... People expect to fly from UK to Ibiza/Greece/Turkey/Spain/Italy etc for well under £100, which is less than it was 30 years ago! inflation alone would mean that the minimum such a flight would cost should be somewhere around £350 now, probably more...no wonder you pay extra for a hold bag, a meal, etc...and with a 29 inch seat pitch, making anyone over about 6ft crippled by the time they get off the plane!
Flying in Europe short haul? no thanks, I'll take a Eurostar, and a TGV anytime...
