<s>[INST] The next text is a question of a member of the European parliament:"On‑line flight reservations contain more and more misleading information and entail extra charges which are automatically imposed (‘administration fee’, charges for checking in luggage and use of credit cards,etc.) and which considerably push up the prices stated in the airlines’ alluring — but misleading — advertisements. In addition, some airlines force customers to pay higher prices by claiming that the cheapest seats have already been sold, whilst in fact the aircraft is virtually empty.  Can the Commission, which has for many years been committed to taking action against companies in order to force them to comply with the existing regulations — in particular concerning misleading advertising — finally provide details of the long‑promised action, measures and sanctions it intends to take against the flagrant abuse perpetrated on defenceless consumers?"
