Thanks for the clarification. You are, I think, quite correct with regards to LHR. I imagine the AY codeshare is because EK don't fly there (yet) and it would mean a 3 hop journey via DXB/LHR or various other European cities served by EK. The EK booking website gives the last leg on Flybe, e.g. FRA/HEL, ZRH/HEL etc.
