Could not reach a Sun Country rep nor could I get a satisfactory response from SC regarding what gate my flight was departing, from DIA, flight 652 departing for MSP on July 23, 2021. I checked in on line. There were a bunch of us all clustered around the departure/arrival board. We found it by checking with a DIA rep. When we got to the gate, the gate agent said they were aware of the problem and were making announcements overhead. We could not hear these due to so much ambient noise. Please solve this problem. Also signage for SC not great either. User's recommendation: Check in and ask agent for gate number.
