One will work much harder every day.
JNB-WDH leaving 06:15 in the morning already, then just 25mins turn-around, back at JNB 10:55, then only 35mins turn-around at JNB, do JNB-WVB back 16:45, turnaround 35mins again, do JNB-WDH with 35 mins turnaround in WDH as well, arrive back 22:20.
So turnaround here is very little, while the other one is stupidly longer.
At the moment DH4 is turned around at GRJ around 30/40mins, is it really necessary to have the CR7 standing scheduled 1h35mins? This after coming down JNB-GRJ in 2h05...which I guess will rather be more like 1h45...so could stand for almost 2hours. The last SA flight before this from GRJ is Airlink BAe to CPT at 17:45. So I feel why do they have to keep this aircraft on the ground for almost an hour longer than necessary, and then have to pay the groundstaff that extra...as well as the crew (because it's not doing other flights after that)
Scheduled times for the other routing is:
07:50 JNB FBM 10:20
11:35 FBM JNB 14:05
15:15 JNB GRJ 17:20
18:55 GRJ JNB 20:45
That seems to be too much fat for in case of delays, since the other aircraft is operating almost anorexic!
