The International Air Transport Association, known as IATA, suspended Air Zimbabwe for non- payment of booking fees, U.K.-based Nehanda Radio said, citing an IATA statement.

The state-owned airline owes IATA about $280,000, Nehanda Radio said on its website. The ban won’t affect Zimbabweans already booked to fly on Air Zimbabwe, though foreigners traveling to the southern African nation may encounter difficulties, Nehanda Radio added.

Pilots employed by Air Zimbabwe ended a monthlong strike April 21 after protesting unpaid salaries and allowances dating back to February last year.
