LAD-CPT-LAD. Check-in easy no problems. The flights were uneventful but the interior of the planes were very old and it appeared that at least one armrest in each row was broken as they were taped up or visibly falling apart. Seats from LAD to CPT were quite comfortable but there was no IFE for a nearly 4 hr flight. CPT to LAD the seats were very uncomfortable. IFE on this flight on drop-down screens but the audio was played over the PA system so it was difficult to hear. Overall customer service was typical of Angola - non-existent. I would only recommend for the convenience to CPT from LAD.
