Haven't a clue
Current routing for my 5 trips a year is to LGW thence to LHR.
I'd be fascinated to see which airline this is with............
but BA's enthusiasm for cancelling domestics
Seems to lack a certain logic.
PS I use BA MAN - LHR twice a week (for 14 years) and have no qualms at all - I'm on the 1403 this afternoon............
