Have 2 choices to go to ZRH

Unfortunately for the day I want J class direct to ZHR is not available on AP

1) YYZ - LHR - ZRH on AC to Heathrow, LX to ZRH (currently booked)

2) YYZ - EWR - ZRH on AC to EWR, and the LX Privatair contracted BBJ/2 to Zurich.

Would cost me a change fee to switch, but if anyone has done both, is it worth it to try the BBJ/2?? An all Business class jet sounds interesting, and who knows, the tax reduction may offset the change fee( but not counting on that.

Of course it saves going through LHR, which although is not until January, the thought of getting stuck there is front and centre right now.

I am then continuing on ZRH - BKK and both flight combos get me in ZHR about the same time.
