ECU held their nose on Charlotte joining because of the TV market. No way they will stand for App St. Very low TV market but strong fan base, ECU base is slightly larger and has better attendance. App is not an easy place for travel. To fly a B737 close you have to go to Hickory NC (6400 x 150 runway TUPilot could provide better insight but think you have to get certain clearances before hand) at 36 miles away or Tri-Cities (Bristol TN 8000 ft runway) is more likely 72 miles away but it is a hard drive over the mountain. My guess is for a football team would fly to Charlotte 95 mile drive or Greensboro 128 mile drive and a couple of hours bus ride. Neither option is ideal for travel.
ECU is still aching from their loss to App (27-24) but since then App is in tail spin. They barely held off Charlotte (26-21) and then lost last weekend to ODU (10-3). App Fans are vocal and upset.
JMU is new to FBS but is a better TV market and is coming off of multiple FCS Championships. They and NDSU are the best football up and comers IMHO.
73 can operate on that runway. SNA is 5700... But it also depends on elevation and 73 version (700, 800 NGs or MAX or SFP... and so on). Plus, almost every flight done on those short runways is weight restricted.
I never flew with the team when I did the equipment stuff so I'm not sure how full it is, but gross weight, aircraft specialty, and elevation are going to be the biggest factors for a runway that length.
You also have to have an operator willing to do it... And customers willing to fly on that operator
