Chautauqua Airlines operated up to 12 Embraer 135 and 145 jets out of Milwaukee. Frontier began branding these flights as Frontier Express in the spring of 2011. With the pull-down of the Milwaukee hub, the only route that continued to operate with a Frontier Express ERJ-145 jet was Milwaukee to Rhinelander. However, Frontier service to Rhinelander ended on January 3, 2013, and Chautauqua transferred the remaining aircraft to other partners.
They lost my hotel reservation the 1st time a couple of years ago.  I received a credit of $100 that I was told wouldn't expire.  Tried to use it for my flight a couple of days ago and it expired.  I booked my flight and paid extra to be able to choose my seat.  When logging into United to choose my seat, the only option other than where they put me (last row of the plane by bathrooms and in a middle seat) was to pay for a more premium seat, paying an extra $50.  Called Travelocity in hopes that someone would help make it right, but there was nothing they could do.  Customer service at it's finest.  I thought I would give them another chance but this was the last.  I've never EVER had a problem with Priceline and will continue to use them.  Just booked my car and hotel with them when Travelocity could have rectified the situation and got that business as well.
The initial JetExpress partnership with Mesa ended in January 2004, when Horizon Air was selected to operate the routes. Horizon utilized slightly larger CRJ-700 regional jet aircraft on these routes. In August 2006, Frontier and Horizon ended their partnership.[64] While Frontier was generally pleased with Horizon's operation, the carrier decided that it needed to revisit the agreement and find a provider with additional regional jets to grow the operation. The last of the CRJ-700's was returned to the Horizon Air fleet on November 30, 2007.
