I've done that a few times too, but for people who are new to this the idea of going to a badged BA office when it opens at 5am or so may be less stressful than depending on an individual to turn up and find you in the middle of the night in a strange airport. Of course I have Mrs Kamal's mobile number in case of difficulty (which there has never been).
By the way, I have always found that the people at the transit security have been very reluctant to let me through when transiting from the BA flight to the BA flight back again. On the two times I have tried it I gave up, paid my $15 and went round through landside... maybe the security guy was looking for me to pay the $15 to him?
