First of all - thanks to everyone for all of the great information, this is my first post but I have been trolling for awhile. Second, I have an opportunity to do my first MR in March, leaving from WAS/PHL anytime on 3/20, returning 3/23 or 24. I do not need to be in SLC until midday on 3/21 and I can leave anytime 3/23 or 24. Anyone have any thoughts on a MR on DL? I have been playing around on ITA/Google flights, but haven't really found any true MRs. Thanks again!
