To anybody considering using reward miles to upgrade to Lima - a piece of advice...don't do it. This flight used to be true BF service on the 752. I recently cashed in miles to get a BF first seat and was apalled when I got on the plane and saw them upgrading elites. The true BF service was gone - basically transcon flight service. The problem with this is the website shows it as a "BusinessFirst" reward. When I sent several e-mails and tele calls to CO to explain that I "paid" for BF service but received standard FC service I was rebuffed and basically ignored. Morale of story - when cashing in for BF service - confirm it actually is BF.
