As BACF have been using up to three Eastern aircraft, I am not sure the additional 4 E90 will mean a lot of expanson route-wise. Probably T3's S20s will be replaced with two BACF E70 which in turn will be replaced with two of the new, larger E90 on the routes they currently serve. Same could happen to the E70 currently leased from Eastern. Unless the Loganair S20 stays on the IOM route and does not get replaced in 2019, this would mean just one additional airframe which will not have much spare capacity with two daily FCO flights plus an additional ZRH flight already scheduled.
