This pretty much says everything. June 8th is a particularly bad day for availability on LAS-ATL flights. Once you exhaust non-stop LAS-ATL options and have to start using double-connects to get to BMI (as the only flights are through ATL), it's not surprising there is only Y inventory open. High demand (possibly due to some event) and booking too close in.



Once in awhile, you need to consider other options than DL.
