Aer Lingus is too small to survive on its own.
Therefore every carrier the same size or smaller is doomed? Utter tosh. Aer Lingus will survive if it can get costs under control and prevent revenue falling too far. They have survived against a certain Ryanair in Dublin for a while now.
What is this arbritary size that you need to attain to survive please? Do enlighten us. Now I was going to book Loganair for a hol in September but by this absurd logic they are screwed as well so I won't bother now.
with recent falls in demand for air travel = fall in demand for slots
Not true across the board as every time this happens, Heathrow remains annoyingly full as new operators pay silly money to move in.
