Tom,
Its 1 FA per 50 PAX, so anyone could get away with 100 seats and 2 FA. While E190s would be perfect for a lot of routes I dont know how keen EI are to introduce a second tyoe to short-haul ops. Given the size difference it would be pretty straightforward from a scheduling point of view and CC could be cross trained. But surely EI would have looked at A319 for some of the A320 order. I would love to see a smaller EI aircraft though.
JER...I think it could be quite popular BHX has disappeared from the timetable for two days a week, so it might happen, I guess.....
