I would NOT buy this fare, UA is committing fraud selling them. It used to be they were just woefully inept and ripped off customers during IRROPS now its just plain and simple fraud as they tell you are buying biz/first but file the fare as econ fare, its a complete bait and switch. There was a thread about this a few days ago. You cannot see the fact they are selling you a coach fare from .bomb or any other booking site, only if you have access to the GDS.
