Im fuzzy on it, but I thought they had a mostly first-class config. I do know that they baked their own chocolate chip cookies onboard.....a staple of their service. They had flights to PHX, which is the only reason I know about them.
One class, excellent service, warm chocolate chip cookies. Flew them a ton. There was a price differential but I'm not sure how much as I never comparison shopped - if I was going somewhere they went, that's who I flew without exception, no matter the cost. I loved them.
