Phoning BA at Midnight GMT

[Definitas]

I’m looking at phoning BA tonight at midnight GMT to add the return leg to an outbound flight that I made a few weeks ago. I have read where people have done this successfully but I’m not sure which department I need to call (i.e. is it general booking or is it BAEC?)

Can anyone please suggest A number that definitely works?

Thanks

If you have a look at the articles and threads on doing this (especially the “booking the return with the 241 thread”) there are numerous posts about the best numbers to call currently.
