As a United Airlines million mile lifetime gold, I'm pretty committed to flying UA when I can for a variety of perks....Now, that BOS is my home airport rather than EWR, JetBlue would certainly be a possibility for our yearly trip to France. What I find surprising is the very subdued response to this announcement of Flyertalk.....only 7 comments so far before this one. I would guess when UA announces a new destination of this sort (i.e Athens), there would be dozens of comments the first day. Perhaps that's a reflection of the JetBlue forum having reduced number of followers, perhaps because JetNlue is primarily a domestic airline.
But whatever, this is great news. And I'll be interested to see how fares price out with even more seating.
