I was watching the flight tracker for the Rapid City airport. I noticed that two flights had different flight patterns.
Flight 6837 which is an UAL flight operated by sky west which was to be a RAP-DEN flight turned out to be a RAP-GJT.
Flight 5190 operated by Great Lakes Aviation was to be a RAP-DEN but turned out to be a RAP-CYS.
My question is there something happening in Denver today that is diverting flights to other surrounding cities?
