There are still some Brits abroad who want to come home but can't because flights don't exist and they were not able to return at the time flights did exist. I am one of those, stuck in Israel, caring for an elderly and recently cancer diagnosed parent. The situation now being stable and with a care package in place, I am now able to leave; but unless I take a 44+ hour trip from TLV to EWR, EWR to LHR and LHR to Manchester I have no option until other routes reopen. Do I want to spend all that time in aeroplanes, and in an airport terminal (17 hours stuck in Newark with the virus coursing around New York...); not really.
So please think before suggesting airports and borders should be closed. I want to get home..
