So, just to clarify, you know that 1774 is an issue. It's really the last good connection for any flights into or out of ATL. It's thunderstorm season right now, which usually means late flights and missed connections. RDU also has between 11 and 13 flights daily to ATL alone. Plus you say there are mechanical issues with this flight. Why in the world, having all this knowledge, would you book on 1774? I'm not saying take the 0600 departure, but there are two flights prior to that one that can get you to ATL, give you the cushion to get there that night? That just makes zero sense.
