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?
IIRC, they give it a flight number in the 9000s (or 9900s maybe) for ATC purposes. It also happens when you have major delays on international flights, or interrupted segments (e.g., MX stops in Canada) that result in the "same" flight operating twice on a particular day.
