Still a funny coloured sky in BASSA land I see.
No one really knows but I would suggest that the loss of ST, albeit provocative, is clearly up to the company as it is a perk not a contractural right.
As to paying back money to those who lost it I am afraid that it was their choice to live away from BA and not the companies responsibility to cater for their travel to and from work.
Surely a decision in favour of commuters from a court would be discriminatory against any person not requiring ST utilisation to get to work.
Don't hold your breath.
