Getting the right livery on that aircraft would have been a nifty trick to make that work, since the same E190 did OMA-MCO as Midwest, then MCO-OKC-MCO as Frontier, and then MCO-OMA again as Midwest.

Just so they get a painted jet on both of those E145 lines that day -- sending a generic bird is not much better than sending a Midwest plane. Hopefully they don't have any irregular ops which force a swap to a non-Frontier aircraft.

Best laid plans sometimes go awry, however. Several years back in the all-Beechcraft days of Skyway, Mary Tyler Moore was booked to fly MKE-CMH. There was one aircraft with an inoperable VCM which meant the plane had no A/C and if I recall correctly, had no pressurization which meant relatively low altitude flying. Usually when a plane had a written up VCM they tried to keep it on shorter hops, or at least avoided the longest hauls to Nashville, Columbus, Cleveland and Toronto, until it got fixed.

Well...as you can guess, last minute irrergular ops put Mary on an unpressurized BE1 flying at 8,000 feet without A/C all the way to Columbus in summer. She was on Leno just a few days later, but no horror stories.
