It is very sad to see people start to squabble, particularly those in BA. If you attended the BALPA video phone in, you will recall BALPA legal advice was to a LIFO+ because of case law in the not too distant past. I have been made redundant before from a flying job and LIFO+ was used. Unfortunate it was to me at the time.
A good legal summary is here:
LIFO: ?last in first out? as a method of redundancy selection ? age discrimination
