Benefit in Kind
Overlooked on this subject is the fact that BA annually sits down with HMRC and "agrees" a payment to the government for the benefit derived by employees and retirees from ST.
Also, in answer to an earlier post when ST09 was introduced it was stated that ST represents a NETT cost to BA even taking into account ID90% revenue as well as that derived from non BA staffers travelling on ID tickets. In part this is why some pensioners will loose out come 2014 when ST is withdrawn from them as a result of being either early leavers or retirees with relatively short length of service. It was sadly a cost saving measure. Rather short sighted IMHO. Let's hope we can influence a change for those affected prior to April 2014.
