UGANDA is threatening to withdraw from a regional airline co-owned with South Africa and Tanzania unless routes for state-owned Uganda Airlines Corporation are guaranteed. If no guarantees are reached Finance Minister Gerald Sendaula will issue a notice of Uganda’s intention to pull out of Alliance Air because the regional airline has made UAC unattractive to bidders who want to purchase it by March, parliamentary sources said. Alliance Air, trading as Africa Joint Air Services, is owned by the three governments and their national carriers UAC, Air Tanzania Corporation and South African Airways.
