There are three 777s in this configuration, strictly speaking not BA aircraft but AML a/c leased to BA. (Flown by BA flt crew, but with AML cabin crew).
Predominantly used to Caribbean destinations they also fly to Tampa and Cancun.
The AML agreement ends Summer 2002 and the a/c will be integrated back into BA at that time, reverting to standard config.
That's good news, but the bad news is that the AML cabin crew then find themselves jobless. Particularly sad because they are a very hard-working, good humoured bunch.
