All will be massively affected for the next 18 months. If we were still owned by Peel, this would be the death nail. Under our new ownership, we can maybe hang in there longer until normality returns.
As said before, old normality is probably 18 months away and by then we may all accept a new normal.
I certainly think the airports planned attraction of a lo-co will now not happen for a couple of years. We also need Eastern to survive.
As for Leeds and Newcastle, they will survive but they will take a big near term hit IMO.
