I found a fare available on ITA but the two Delta phone reps I spoke with can't recreate the price.

The itinerary is as follows:
Feb 1 DL1187 BZN-MSP
Feb 1 DL264 MSP-AMS
Feb 2 KL3180 MSP-SVO

Feb 12 AF9715 LED-CDG
Feb 12 AF378 CDG-DTW
Feb 12 DL1055 DTW-MSP
Feb 12 DL4644 MSP-BZN

The fare basis is:
Fare 1: Carrier DL ULWB67US BZN to MOW
Fare 2: Carrier AF NLXB77US LED to BZN

Pricing out at $1351.30/each for 2 pax.

Delta phone rep can recreate it but with a fare brake in DTW and a B fare DTW-BZN pricing it at $1850.

Any suggestion on how to get this to book?

Thanks!
