This wording is the current wording and not from Oct onwards on ba.com it says

"Changes to the carriage of sporting equipment
Sporting equipment will be included as part of your free checked baggage allowance.
If the number of bags exceed your free allowance you will be charged the excess baggage rate for each extra bag.
The heavy bag charge Ģ30 ($50) will apply each way to all bags more than 23kg (51lbs) and up to 32kg (70lbs).
All sporting equipment (excluding the not acceptable for carriage list) will be accepted for travel only if they are packed correctly within the maximum weight and reduced maximum dimensions of 190cm x 75cm x 65cm (75in x 29.5in x 25.5in)."

So it sounds like the size restriction is now important compared to before and also the number of bage you carry. Watch out you donīt want to get charged for a boot bag

We will see once the policy comes into place and the wording is updated on ba.com
