I suppose BRS and Jet2 has been made possible now as no doubt EasyJet are probably reducing it's outlook into 2021. With a shrinking fleet, I would imagine the slot constrained airports like LGW, CDG and AMS will be protected at all costs.
With optimistic projections from Wizz, Ryanair and now Jet2 it would seem on next summer, it begs the question really have EasyJet potentially put themselves in an incredibly difficult position even to recover long term growth while competitors pile on capacity, albeit driven by discounting. And doesn't bode well in my mind for EasyJet holidays to have a meaningful impact on Jet2.
I do wonder now if LGW could be on the cards for a Jet2 base as opportunities will surely become available there.
