Further to my post dated 13th July we flew Air Link JNB-MUB on Friday. It was a very fast check in with one queue for all Air Link flights and many desks open. There were a fair number of people but we got through in about 4 minutes. The flight departed smack on time and we arrived 10 minutes early. One hour twenty instead of two hours with Air Bots. Very smart aircraft (BA146) and crew. Very nice chicken with sweet chilli baguette. Good selection of drinks - 4 different beers, wine and soft drinks.
The whole flight was operated in a very professional manner - AND we got our luggage on arrival at MUB
They have my vote.
