I'm just sat here doing the wife's MR for *S... target is 19,000 or more.
At the moment, it's all based on JSWISSUK / JSWISSDE
LHR-ZRH-MUC-ZRH-LHR
MUC-GVA-ZRH-VIE-ZRH-GVA-MUC
I get the mileage out at 23,750 (inc. her 25% bonus), and the cost is ~GBP760. That's flying out and back over a Saturday/Sunday in August.
