(22)The main characteristic of a package is that there is one trader responsible as an organiser for the proper performance of the package as a whole. Only in cases where another trader is acting as the organiser of a package should a trader, typically a high street or online travel agent, be able to act as a mere retailer or intermediary and not be liable as an organiser. Whether a trader is acting as an organiser for a given package should depend on that trader's involvement in the creation of the package, and not on how the trader describes his business. When considering whether a trader is an organiser or retailer, it should make no difference whether that trader is acting on the supply side or presents himself as an agent acting for the traveller.
