I too have trouble getting good MR's out of DEN.
I just noticed a "fair" run to San Juan
$304 all in for 6240 EQM = 4.95 cents per EQM
Fare code SRONX1 looks like you could leave on a Wednesday and back on Monday. I tried Aug 10 to Aug 15 th and almost grabbed it- WORK keeps interferring with my MR's
Might be a fun weekend in Caribbean for somebody
