I take them on an average 1.5 times per month. Some of them
cannot be helped by the aircon probs and some passengers could not
bear the vibration and the dusty seats.
To me, their performance quite ok. But, the interior design
wasn't what i like. It may have been TIBS mistake of not
refurbishing the interior during the 'transformation' from NAC to
CAC in 2001. This may have started the 'complaints' ball rolling in
my opinion.
TIB840A can still be seen on 852 and the rest could be spotted
on 187.
P.S: Do look out for cameos. Common Services: 167, 178, 965,
969, 980(TIB847G weekend perm)
