When disembarking my flight at JNB
on 31/7 I was surprised to spot a parked F28 in SA
Airlink colours. Thought for a moment the beer I consumed on the flight went to my head! Your ticket confirmation seems to confirm what I saw. Maybe a short term lease for an extra capacity period? Hopefully it works out that way for you. Personally I would much prefer a classic bird like the F28 to the usual J41 or EMB! Let us know the detail of what transpires.
