I had a quick look at the Thomson Brochure and it does look like there are going to be 3 aircraft based in BRS for Summer 2014. There seems to be a gap on a Saturday morning but Thomson Lakes & Mountains have yet to release there S14 schedule so a BRS-VRN rotation will more than likely fill that gap.
There are new routes to Kos, Marrakech, Bourgas & Kavala. There are increases in flights as well compared to Bristol's S13 schedule.
The schedule for BRS for S14 is as follows:
