OK, really remedial ATC question here:
What happens if STL-DFW is delayed inbound with no connecting pax to DFW-SJO -
and DFW-SJO is loaded and ready to go on time?
How does ATC refer to the DFW-SJO flight? Seems like you could theoretically have AA2167 on final approach and AA2167 taxiing out for takeoff at the same time? I realize different controllers would be handling the two different planes, but do they do anything else to distinguish between them? Especially if they are both 757's?
