Well I suppose BHX does have a new link to the U.S with Biman flying to JFK - however at 2 x weekly I hardly think it will appeal to a huge number of BHX originating pax or see a huge increase in pax flying to NYC.
BHX must be feeling somewhat red-faced with their shiny new runway extension but no apparent interest from U.S or Canadian carriers in operating from it. The commercial aspects of flying from BHX across the pond save for the long standing single UA service simply can't add up although as chinapattern points out, one would hope that BHX have realised this. Being sandwiched between the multiple daily flights options available from LHR and MAN as well as competitively priced connections with EI via DUB to the U.S can't help the situation either.
