A friend and I are flying from BNA to MEX for a long weekend soon. We booked basic economy tickets on American Airlines roundtrip. My friend's work changed her plans, and her work is booking a separate ticket for her to fly out earlier on Sunday than anticipated. Is this going to cause an issue? Can she still fly down on the roundtrip ticket and fly back separately? Does this being international complicate anything? I've read some about airlines reacting negatively to "throwaway ticketing", but we aren't trying to deliberately avoid paying them anything, so I'm unsure how to proceed. Our tickets are also on one booking if that information helps. Any help would be much appreciated!
