WN recently added daily Nonstop service MSP/LAS.

Our flight last week was sold out and originated out of BWI, it had 58 through passengers MSP/LAS.

Our return LAS/MSP originated at LAS ( and was also sold out) so we boarded an empty plane.

Seems the MSP/LAS flights may always originate at another airport so I was wondering if there is a way I can see in advance if this is the case.


Thanks
