BAConnect had started a DUS route a year before they pulled out of BRS in the spring of 2007 following Flybe's involvement with the demise of BACon. That resulted in a number of other BACon routes from BRS also disappearing including other German routes to FRA and MUC.
bmiregional now flies FRA and MUC and also flew MXP (another of the BACon routes) but as as been previously discussed that one seems to have been pulled permanently despite its loads being largely on a par with the other bmir routes form BRS, so presumably the yield was not up to scratch.
It might be thought that if MXP didn't succeed then DUS would be doubtful but there does seem to be further expansion afoot at BRS with this airline so who knows outside the company? bmir does or at least did (they may still) seem willing to try German routes from BRS with HAM and HAJ as well as FRA and MUC, although HAJ no longer operates and the HAM and BRS catchments have important business links with the likes of Airbus.

Going hand in hand with the four new routes is the announcement of an additional based aircraft next summer or at least for part of it which will make 12.
Given that GIB and OPO are 3 x weekly and ACE and CTA 2 x weekly there does seem scope for further route enhancement if the aircraft is to be utilised fully.
