I don't think these bare figures mean the route is setting the world alight, especially when compared, for example, to what the CO EDI-EWR achieved in its first year when it commenced in summer 2004. 75,000 was perhaps a modest target.
For the period May-Dec 2005 the BRS-EWR seems to be running two or three thousand or so pax behind the CO BFS-EWR which commenced a week later. These figures are not definitive because those for December are only provisional.
However, we know the real measure of success is the yield and that will of course be a commercial confidence.
The BRS route seemed to have a slow start with gruesome predictions in another aviation website MB that it would not last long. Apparently the major problem was in getting American pax to use it, or even know about it. Anecdotal evidence suggests this is gradually being overcome.
