Go to DeltaNet-->Departments-->Delta Connection-->Departments-->DC Air Operations-->Air Ops Dashboard and you will see the up to the minute status of all DCI carriers and why they cancel. You can go even deeper if you go into the OCC page on the DC Air Operations page and find the link that says "Flight Legs Cancelled with FAM remarks" section. Recently SKW has been canceling more than others due to lack of crews out of MSP for the most part. Mostly to cities like Dickinson, BJI, BRD, etc. Endeavor cancels quite a few as well mostly due to crews being stuck somewhere after east coast weather events and pilots timing out. ExpressJet has the most cancelations due to Mechanicals.
