According to flightaware, Friday (2-8-2019) and Saturday (2-9-2019) The ICN-ATL legs are making a stop in MSP with A350-900 aircraft: N507DN (on Friday) and N502DN (on Saturday). I know MSP is getting its own N/S MSP-ICN that begins 2019-April-01, but with B777-200ER's (post refitting.... aka 7HD's). Guess I'm at a loss as to the why as "diversion" word is not stated in flightaware detail. I'm staying away from doing any speculation at this point.
