AIR ZIMBABWE has increased its flights from Harare to London from three to five a week. It will also resume its weekly service to Frankfurt, according to an airline announcement. In addition a new service will be introduced to Rome in November, and between Harare-Lubumbashi-Kinshasa-Brussels later in the year. The carrier has also entered into an equipment and service agreement with Zambia Skyways for all its flights to London, which is seen as the first step towards a possible code-sharing agreement.
