Hi - I'm traveling from Vancouver to Entebbe on a one-way Aeroplan reward flight later this year. The routing goes YVR-SFO (UA), SFO-IST (TK), then IST-EBB (TK). The whole thing is in biz class.

The IST-EBB segment stops for an hour or so in Kigali before continuing on to Entebbe. I've changed my mind since the booking, and now want to go to Kigali instead of EBB.

I can call Aeroplan and make an official change of course, and pay the fee, but in that the plane I'm on is already going to Kigali, can I just leave the reservation as-is but get off in Kigali? (I won't have any checked bags).

What if I just tell them once I'm on the plane, or when I'm boarding that I want to get off? I'm guessing the answer is No, but you never know...

Thanks!
