Was just looking at flights to New York and interestingly BHD now undercuts BFS by a fair bit and sometimes even DUB. Fares available at £401 for a large part of the year via AMS using the imminent KLM cityhopper to connect.
Now obviously the non-stop flights from BFS and DUB are preferable to most people but it does give another option for those willing to give up time to save a bit. In that sense it can only hurt the UA flights from BFS.
