The direct answer for anyone searching a lounge at Dschang Airport is no, and the underlying reason is the airport's service picture rather than a missing amenity at an otherwise busy field. Dschang, a university town in Cameroon's West Region, has a small airstrip that has not supported regular scheduled airline service in recent years, so there is no ticketed passenger flow of the kind a lounge would exist to serve.
That absence of scheduled service is the real story here, more than the strip's physical size. A lounge is built around passengers checking in, clearing security, and waiting to board a scheduled flight, and Dschang's airstrip does not currently host that pattern in any consistent way. Without regular airline operations, there is no terminal infrastructure, premium seating area, or anything resembling a passenger lounge to check for, and travel to and from Dschang in practice runs mostly by road rather than by air.
For genuine airline and lounge infrastructure connected to a trip through this part of Cameroon, Douala International Airport (DLA) is the realistic anchor. Douala serves as the country's main economic-hub airport, with a considerably larger volume of domestic and international traffic, and it carries the kind of airline lounge and card-network access that a small regional strip like Dschang's was never built to offer. Travellers with business or family ties to Dschang typically fly into Douala and continue by road rather than expecting to fly directly into the town itself.
Because scheduled service at small Cameroonian airstrips can change without much notice, it is worth checking current advice directly with any operator or travel agent before assuming Dschang has active flights at all, rather than relying on older listings. Whatever the current flight situation, plan any lounge access around Douala, and treat Dschang's own airstrip as infrastructure for occasional or charter use rather than a stop where a lounge visit would ever make sense.
