Tomorrow I am flying from BWI to ORD (flight NK761), then ORD to MSY (flight NK815). Right now 761 is listed as arriving at gate L11. Flight 815 is listed as departing from gate L11. 761 lands at ORD at 7:35am... 815 is supposed to depart at 8:05am, which is cutting it close, but shouldn't be an issue as long as my first flight is not delayed.
My question is, how can two different flights, with overlapping arrival/departure times, be scheduled for the same gate? What if we aren't able to deplane from my first flight because my second flight is at the gate and boarding?
