Must be a bad week for US Air. I was scheduled to fly US 1764 today from ATL to CLT. Boarded and everything but had to wait another 20minutes for them to diagnose an oil leak. End result - flight canceled. Was quite a mess at the gate with everyone trying to get rescheduled.
They rebooked me on Delta and I actually got home only 20mins behind schedule since it was a direct flight and I didn't have to connect thru CLT.
