Return Qatar Airways flights, via Doha, are now available from Heathrow, Gatwick, Manchester, Edinburgh and Dublin.
Until now, Riviera has only offered South Africa flights via Heathrow. All new flight options are available at the same price, or less.
Riviera is marking the launch with a new agent incentive. Throughout March and April, all trade bookings for South Africa will see agents entered into a prize draw to win one of four £100 John Lewis vouchers.
In total, Riviera is offering 11 departures on its 16-day South Africa tour next year from January through to November.
