Whilst I suspect this pandemic has a way to run yet, EZY took a position fairly early on with long term cost efficiencies by closing bases as STN, SEN and NCL. It would appear they have looked at the near term future as best as anyone can and put measures in place to reduce overheads - they are currently anticipating operating at around 20% normal traffic levels over winter.
Any "sweeteners" from airports may see the traffic return quicker in those places next spring but I get the impression EZY are battening down the hatches now whilst planning for the longer term in the remaining bases. It is always possible that the situation could take a turn for the worse over the winter and they would then need to revisit the base situation again but for now, I personally don't think this will happen.
