In US domestic air travel, do single airlines (= single carrier) ever have more than one "physical flight" scheduled to leave the same airport, on the same day, with the same flight number? If so, can two flights with the same number of the same carrier be scheduled to leave at the same time?
- I don't mean rescheduling of the same flight as the result of a delay.
- I don't mean technical problems causing the same physical flight to be displayed twice on a list of departures.
- By "physical flight" I mean one single unique physical airplane with its crew passengers and cargo.
