Bit of an interesting mileage run opportunity. (Are we still calling it mileage running even though it's dollar spend?...) In any case, it's a decent opportunity to get some EQMs.
$103 from MSP to CLT via PHL on one leg. Can't do anything to make it a day trip or 1-nighter. Just pure flying.
Lots of availability in October and November. Some in September and August.
