Regulation (EC) No.2111/2005 establishes a list of air carriers which are subject to an operating ban within the European Community. British Airways is required under this regulation to publish the existence of this list on its website. This list, and some associated information about the Regulation, can be accessed from the UK CAA website.
Additionally, the European Commission maintains and publishes the detailed list of carriers subject to an operating ban on the European Union Transport website.
Flights operated by carriers on this list are not available to be booked via the British Airways web site, ba.com.
