Where do I buy extra baggage?
Buy it in British Airways Manage My Booking / Find my booking after retrieving the reservation with the booking reference and passenger last name.
When should I buy extra baggage?
Buy before check-in if possible. After check-in, extra bags can only be added and paid for at the airport.

British Airways allows up to 10 extra bags per passenger for personal-use items. No checked bag may weigh more than 32kg.

The extra checked bag price depends on destination and on how many additional bags are added. The live amount is shown in Manage My Booking for the itinerary.
What are the overweight and oversized baggage rules?
Bags between 23kg and 32kg can incur the heavy bag charge. Oversized checked bags may be accepted up to 190 x 75 x 65 cm, and British Airways asks passengers to notify the airline at booking or at least 48 hours before departure for oversized bags.
How can I pay for extra baggage?
Eligible bookings can be paid online with a card, Avios, or a combination of both. After check-in, Avios cannot be used for airport extra bag purchases.
Do partner-airline or codeshare flights have different baggage rules?
Yes. British Airways notes that partner-airline or codeshare itineraries can have different checked-bag allowances and servicing rules, so those flights should be checked carefully.
