They had a few foriegn carriers doing marketing for their flights to JFK
that would give them so many TrueBlue points or a certain price if they flew B6
in the US.
In the cc yesturday, David said that an announcement about codeshares will come in the "not too distant future" and that they were having some snags with the software programming to allow whatever they were going to do, be it full codeshare, frequent flier, etc...
Hopefully they will have some things rolled out by the end of Q1 so that they could get some extra business for the summer months, as if many carriers need it during those months, but it should help. David also mentioned that it would not start out to be a very big contributor to their business at first but in a few years it could be a very valuable and succesful program.
Hope this helps.
