We are checking in for a AA flight that leaves the domestic ATL terminal at 5.36am. We have an overnight layover and so are staying at a hotel next to the GICC skytrain stop. We were anticipating getting to the airport at about 4am, but that would mean getting the Skytrain at just before 4am. I know it runs 24h, but someone mentioned that it doesnt run 1am to 4am - is that right? Does anyone know how long we might have to wait at just before 4am?
Thank you
