I flew on Boutique Air once. It was great. Small plane that holds 8 passengers I believe (no FA's), and they have self-serve snacks and drinks in drawers at the front of the plane. As far as I know, they have no relationship with UA. I would guess it's a bug in google.com/flights
I LOL'ed at the "First Class (A)" fare. That's ridiculous. All the seats are coach (but no middle seats).
