British Airways Baggage Allowance
Passengers exceeding their baggage allowance (over 23 kg) will be charged for excess baggage at the rate on the day of travel. This is currently £65 if over 23kg for Essential, Economy, and Premium Economy fare holders. The £65 is a one-off charge, so if the sack weighs over 1kg or 11kg only a one-off cost of £65 is charged.
If you have excess baggage why not use a house-to-house baggage conveyance service like AiroLuggage?
If you purchase from AiroLuggage.com then it will only cost £47 (one way to Spain) up to 30kg for one piece of luggage. Not only is it cost-viable, however, but your luggage is also gathered from your entryway and conveyed to the entryway at your destination. Why wouldn't you use our cost-successful service?
There are 1000s of passengers who already use this service and come back time and again because it's so convenient.
