Was this a route that American flew when they had a sort of hub at RDU ?
May not be too lucrative with Atlantic City (gambling/gaming) next door.
But maybe worthwhile if DL puts on a tag-on city upline or downline i.e.
DCA-RDU-LAS-LAX.
That is not the case; looks like DL had an aircraft that would have been
parked overnight at RDU not earning any money for 4 nights sitting
idle ? The 3 nights operating are they weekend nights ?
The wisdom of why things are done the way they are done ?
