Likely in support of the increased connectivity on both ends, a few changes to MKE-DEN
(a) E170's upgraded to E190's
(b) Retimed flights to offer somewhat better coverage through the day. Today two westbound flights operate 1:10 apart, and two eastbound flights operated only 0:35 apart. The new schedule is generally more spread apart.
(c) First DEN-MKE flight moved to 6:40am from 9:30am, so AirTran's 8:00am DEN-MKE is no longer the first flight of the day
(d) More connections at MKE to places like Philadelphia, Cleveland and New York. Some additional connections to Denver's banks, too.
