Even if there is a v shaped recovery - and that is a big if - travel is likely to be one of the slowest recovery sectors. Businesses will be apprehensive, and have found that online working is finally viable. Governments are going to be slow to remove travel restrictions and then quick to reinstate if anything changes which is going to undermine leisure travel greatly.
Even if there is a swift recovery I imagine BA would be happy to focus on high yielding passengers if short of capacity.
