Covid mask
 

Are you wearing masks while actually flying. Is the threat of Covid greater than the ability to put on an oxygen mask if needed.

No.........

We wear masks during turn around, in flight we do not.

Consider what you are protecting against.

If there are two of you sat in row 0 and one has covid, it's a good bet (in my opinion) both will have covid by end of flight, mask or not. Masks cut down transmission probability by some (disputed) percentage, but being sat next to another person for hours even small percentage chances start to add up to a significant risk. Particularly with the new variant.

If you are worried about contaminated surfaces, controls etc., a mask isn't going to help (much, it might, might, make you pause or stop when touching your face, probably doesn't prevent). My guess is that sanitizer is also a pretty bad idea due to the fire risk.

Surgical masks always on both in flight and on the ground. We did setup a procedure in case of decompression and everybody seems quite happy with it. There have been many cases of positive pilots/FAs and so far none of the crew they were paired with got infected, showing that wearing masks makes a huge difference.
