Flying with bikes

got an email from BA.

There is no additional allowance for sporting equipment, but it can be carried free of charge as part of your free checked baggage allowance. We will accept non-motorised bicycles of all dimensions provided they are packed in a recognised bicycle bag. We advise you to transport your bike in a more padded/sturdy covering.

Preparing bicycles for travel:

• bicycle pedals must be removed (or fixed inwards)
  
• handlebars must be fixed sideways
  
• the bicycle must be contained in a protective case or bag
  
• deflate the tyres to reduce the risk of damage.
  
  

The maximum permitted dimensions for carrying bicycles is 190cm x 75cm x 65cm (75ins x 29.5ins x 25.5ins). If it is in addition to your free checked allowance, you will need to pay extra bag charges. You can find excess baggage charges at:
