I'm seeing relatively high rates even starting in early June. PIT -> PIT (both airport and HLE) were somewhere around $40-50/day starting June 1. Probably less telling, but I was also looking at PIT -> PHF and rates were somewhere around $110/day (slightly more reasonable for one way, I guess, but after weeks of $60 one way rates, still a bit jarring)
Using USAA CDP for both.
