Africa - Douala transit on Brussels Airlines?

Hopefully a simple question! I'm due to fly SN Yaoundé-BRU in a few days. The flight makes a stop in Douala to pick up more passengers. Does anyone know whether the YAO-BRU pax get to stay on board or whether they have to disembark and while away a twilight hour dodging mosquitoes :rolleyes: in the DLA terminal?

Thanks in advance,

Passengers stay on board at all Brussels Airlines transit stops within Africa.

Excellent, many thanks!
