Trying to commute open seats the next 3 weeks is next to impossible. Most every domestic route is either at capacity, oversold, or eventually oversold with 24 hours of the flight, down to pilots fighting over the jumpseat. Why isn't United adding more capacity, equipment increase, or frequency back? Clearly there is demand for it. Many of the routes such as MKE DEN, CID DEN, MSN DEN, used to have 3 or 4 737/A320 flights a day. Most non-hub pairings now have 2 CRJ flights a day if you are lucky. Commuters nightmare. Isn't it time to beef up the routes?
