a lot of things could happen here, not the least of which is another jet gets subbed in for DEN-MSN from Denver and the flight goes as normal.

seems to me that they are thinking to fly FAR-DEN-FAR with the original bird in reverse order (essentially they're going to do 6084 backwards of how it would normally be done with a bird that's already in Fargo, and delay both the FAR-DEN and DEN-FAR on account of it).

6084 should be DEN-FAR-DEN, seems like they're going to fly it FAR-DEN-FAR

what happens to 6184 is anyone's guess at this point, but i would set up some flight alerts and watch the "where's this bird coming from" for possible tail number updates.

sometimes having all the information isn't as much of a blessing as we think (posted while sitting in the LH lounge, expecting my flight to EU tonight to be oversold, and it's now suddenly Y4 )
