Back in 2003 till 2008 my travel lite operated a daily a320 noc bhx service and carried 8000 pax a month during peak season. It was a great success for them until the company decided to concentrate on charter ops!
Bmi baby operated successfully and operated against Ryanair on ema route for many years.
Rumours of norweigen setting up a base at bhx for summer 2016 we might get a few flights from them!!😜
