The provincial airport (IATA: MEG) is a single-runway field on the southwestern edge of town. TAAG Angola Airlines runs domestic flights to and from Luanda on a thin schedule — often only a few times a week — and the rest of the time the apron is quiet.
For most travellers, flying is the sensible alternative to the long, slow overland drive from Luanda. Confirm your flight in person the day before; schedules shift, and the airport's online presence is unreliable.
