Was thinking about the flight selection between DL and NW on their respective websites.
So...looking at nwa.com; flight between MKE and ATL...only DL flights are shown (as might be expected).
Checked and they are DL flight numbers (i.e DL 1717)...not what I would expect if they were codeshare or something along those lines.
Looking at delta.com; flight between MKE and MSP or DTW...only DL flight are shown no NW. (connecting thru CVG)
Is there something in place that NW has to show DL flights on nwa.com; but DL doesn't have to give NW space on delta.com...only showing DL flights?
Maybe a stupid question...but strange that it's like that.
Looked at some other random destinations from MKE and it appears the majority are DL flights...no NW.
