Does anyone have the number for the London City Business Team? I've searched everywhere for it but the BA website forgets to actually give the number of the "dedicated helpline".

Friend of mine took the babybus to JFK and left his watch on board. Has a lot of sentimental value so he's v upset, and can't get through to JFK. If anyone has the number of the London City people at JFK that would be even better!

Thanks for any help someone can give
