The Air Charter Association (ACA) reached a milestone last week with the organization now represented by members in more than 50 countries across six continents. Total membership at the UK-based organization is 324, a spokeswoman told AIN.

ACA credits a number of efforts to the growth in membership, which includes members in nine new countries this year such as Canada, Mexico, Kenya, and Finland. It credits a recently announced partnership with 4Air to offer members sustainability planning services and continuous advice to deal with key industry challenges as a driver of that growth.

The appointment of Chris Adams as membership executive also has helped build international membership and wider representation in the cargo and airline markets, the organization said. “It’s noteworthy that many of our new members view membership of the ACA as a key benchmark to assuring their partners and clients alike of their reputation and professionalism,” Adams added.
