I disagree it will be ideal for the LGW run. The only reason the figures show lower pax numbers this last year is the artificial limitation of capacity on that route by the dog of an aircraft placed there after Bacon let their -200 go. The route is often full on peak days and times and the crews and ground staff have struggled with this for a while.
A temporary fix of one of Flybe's 146-200 should show them if the route can grow again to justify one of the EMB195s instead. The Q400 will lose out on the business travellers who choose the 146 out of snob appeal simnply because it's a jet, and trust me there's a lot out there who do!
I believe they are coming over next week to say hello and talk to the crews, so I'll ask my contact to let me know what they say.
