Pool--agree, except that the concept of consumer interest is much deeper than the simple concept that more flights, choice equals cheaper.
As I wrote in my last post, increased EK flights will mean other services (ie. YYC-FRA) get dropped if they siphone off the pax on those flights that continue beyond Europe. Those 10-15% of pax that continue on often make or break a route. In this case a few consumers gain and lots lose.
