Look, if you remember a discussion we had with some folks from Westjet, maybe a year or two ago, we did go into quite a bit of technical detail on the E90, and as I recall, the clear conclusion was that it was not particularly well suited for thin long routes.

At a Mach number of 0.82, it is surely not very efficient. So I would expect that it would often take longer than on a 320, and by more than six minutes, if only to save fuel. Of course on a good day, with the jetstream helping, it will occasionally be less. But that's not the point. We should see statistics, really.
