DONE4 validity.
 

Hi, I'm planning to do a DONE4 and was just wondering if this is valid or if there are any problems which the experts know of. The *ONE* validator says that it is ok.

IST-MAD-EZE-LIM-SCL-BOG-SCL-SYD-AKL-BNE-AKL-BNE-HKG-BOM-HKG-CMB-HKG-LHR-MCT-LHR-IST

I'd prefer to go EZE-CCS-SCL instead of LIM, however service to CCS appears to be reducing and no business class. If I'm wrong and there is Dclass along this route I'd be very happy to hear.

I'm planning to start this in early December, and then have multiple breaks in BNE, before finishing the trip sometime in April or May.
I am in the QF FF program.

Thanks.
Malcolm.

QF fly SYD-BOM if that is of any use to you (6308 miles)
