I really do not think that compulsory redundancy will be required at BA and don't understand why some people keep raising it, particularly on a Virgin thread.
BA's redundancy policy has been updated over the years, the last time in 2015, 9 years after age discrimination legislation came into force. Seniority rules everything at BA, it is not dependent upon age, there are relatively young senior LH P1s and old junior P2s. Joining BA is always a very long term bet. MOA K.11 clearly specifies LIFO as the general principle to be applied if redundancies are required.
I personally believe that an effective treatment for the virus will be found soon. A vaccine may be far away, but much improved treatment needn't be. Confidence will be restored if people know the likelihood of passing away from the virus is very very small.
