Tonyq.....once EZY start ordering more aircraft we could see a smaller aircraft enter the fleet. BE will be very afraid then all over their network, although it won't be for a few years yet!
As far as causing havoc to businesses in the IOM, I think you will find most businesses in the UK use EZY & RYR anyhow throughout Europe. Gone are the days of Amex Gold accounts & business class. It is a very lean outfit which survives and BE are bleeding at the moment.
