I have taken golf clubs to France & Spain many times with BA, my golf bag (put inside a golf travel bag with wheels) was part of my luggage allowance (so no extra), like Alan said, I also managed to stuff all my pockets with clothing, toiletries, golf shoes, spare balls, etc. Then I have my cabin bag & handbag for the more precious & delicates items.
The golf travel bag goes to the out of gauge/oversized drop off and is collected from a special point at the other end. So far, so good.
But BA may change their baggage policy. So read the T&C
As I live near Heathrow, I try to avoid Gatwick, Luton & Stansted.
I am also lucky enough to have free parking @ LHR, as a perk of my long serving years with BAA Heathrow.
