I was looking at the flights that had recently departed ORD and saw ROA363. As I didn’t know what airline ROA was, I clicked the flight to see what it was.
Reno Air. According to what I have read online, Reno Air was bought by American Airlines in 1999. FlightAware says this flight departed from Gate K2, which appears to be an American gate. Is this an American flight identifying itself as Reno Air, or is this just something weird in FlightAware?
