Do you mean airlines which have bases in LHR?
United Airlines used to recruit english crew, as do Japan Airlines, All Nippon and Air NZ. The likes of Emirates and Gulf Air have english crew based out in the Middle East. Not sure wether they take on english males, however did see Emirates crew in LGW the other day and there were some males who looked english.
British Airways are also recruiting for LHR, excellent pay, good destinations - go for it!
