OK, and I will add a few more long layovers. I will only give 3 letter codes, so please work it out yourselves. Some destinations have a combination of 24hr and longer slips due aircraft schedules. The Australian layovers will be later in the year when AKL starts.
MEL, 52 & 24hrs, SYD and BNE two 24 hr layovers either side of AKL shuttle. Long layovers in CMN. ATH, MLA, JNB, KUL, DAC, HKG (later), DME (Moscow).NBO, SIN. MNL
Remember airline schedules can be very volatile, so here today gone tomorrow.
As well as the above their are 24hr layovers in. MAN,BHX,LHR,LGW,CDG, MUC,DUS,FRA,ZRH, FCO, NBO, CMB, and BKK.
In the future LAX,KFK,YYZ,ORD, and SFO.
