I am one of those remarkable people who have actually missed a cruise because of flights. The flight was in April, who'd figure there would be problems. The flight was delayed due to ice on the wings, delayed further in Atlanta due to fog, delayed further due to the drink cart not being delivered to the aircraft, and when we finally got to Miami, they couldn't open the plane door. Well, this was a Celebrity cruise, way back in time, but we didn't get there in time. Missed it by minutes, but the manifest is the manifest, and that was that. It was very sad. Do not let this happen to you.
