Wiggy,
"...is a relatively small part of their overall duties" but nonetheless, an additional duty with associated responsibilities. My experiences with BA C/C in the oversight of UM's has, without exception, been of the utmost highest standard in terms of care and professionalism, however we live in a very different world to the one in which such services were conceived; and that's before you consider the implications of EASA FTL's on a relatively short sector...
I'm inclined to agree with PAXboy's suggestion as well though - this was a special service that made BA different. Very disappointing.
