Frankfurt to Windhoek return Economy. Check in no problem. Flights on time. Seats ok. Food reasonable. Outward leg was the first time I have ever been cold at the back of an Airbus. In flight service disappointing. Crew did the minimum they could get away with. On occasions were actually rude. Uncaring and ignored requests for assistance. Main screen entertainment only with non functioning headphones. I do not recommend air Namibia but they have little competition to push standards up. German 'um pah' music during boarding and disembarking amused the Germans as well as the Brits!
