Looking for 350-400 TP. Can fly in October (weekends only) or in November (can take time off work).

I'm based near DUS and can fly from DUS/FRA/LUX/BRU. Would consider both BA and IB runs.

For the last few days, I've been looking mostly at the BA holidays option to SOF combined with a rental. It comes out pretty cheap despite required pos to LHR. But I think it's too risky overall. As I can't stay the 5+ days required in October, I'd actually be forced to travel SOF-Germany and back on a separate itinerary. What if flight cancellations prevent me from going back to SOF and I'll miss the return of the rental etc. Not so good.

Any suggestions? Can either fly ex DUS/FRA/LUX/BRU or position somewhere. Cheap positioning is usually available to LON/MAD/DUB.
