Airplane blunder

My aunt passed this one on. I thought it was fun and that I'd share with anyone who hadn't previously read this apparently true story:

A woman was flying from Seattle to San Francisco. Unexpectedly, the plane was diverted to Sacramento along the way.
The flight attendant explained that there would be a delay, and if the passengers wanted to get off the aircraft the plane would re-board in 50 minutes. Everybody got off the plane except one lady who was blind.
The woman had noticed her as she walked by and could tell the lady was blind because her Seeing Eye dog lay quietly underneath the seats in front of her throughout the entire flight. She could also tell the blind woman had flown this very flight before because the pilot approached her and, calling her by name, said, "Kathy, we are in Sacramento for almost an hour. Would you like to get off and stretch your legs?" The blind lady replied, "No thanks, but maybe Buddy would like to stretch his legs."
Picture this: All the people in the gate area came to a complete standstill when they looked up and saw the pilot walk off the plane with a Seeing Eye dog! The pilot was even wearing sunglasses. People scattered. They not only tried to change planes, but they were trying to change airlines!
