How does a regular 10-hour flight to Germany from LAX turn into an 18-hour drag?
Simple--the Boeing 747 is five hours late arriving from Frankfurt, and we arrive three hours early as recommended for check-in. As the clerk hands us our boarding passes she adds in passing: Oh, by the way, you know we're running a few hours late! How should we know?
Nothing is posted at the entrance, and once you arrive at the airport you're stuck anyway.
Lesson: Call before you leave home and hope you get correct information about delays.
