This is pre 9-11
The one and only time I relied on a co-worker to share a ride to the airport she showed up late, we missed the flight ..... blah, blah, long story short, her sister waited at the airport at BWI, and of course they would neither confirm or deny the PAX was on the plane.
For me it was a lesson learned. The other one was to leave luggage at home, because if I only had a carryon, we could have taken an earlier connecting flight, but alas, MY bags would not.
