The Competition and Markets Authority (CMA) and the CAA have released a joint open letter reminding airport operators of their legal obligations.
The letter said: “The CMA has recently received intelligence to suggest that some UK airport operators might not always be complying with competition law.”
The CMA and CAA said they were concerned the Airport Charges Regulations (ACRs) were not being adhered to. ACRs require large airport operators to consult with customers on proposed changes to airport charges.
The letter is signed by Juliette Enser, CMA senior director, cartels and Paul Smith, the CAA’s group director, consumers and markets.
