Delta Airlines
At the airport for a trip, I settled down to wait for the boarding
announcement at Gate 35. Then I heard the voice on the public address
system saying,
"We apologize for the inconvenience, but Delta Flight 570 will board
from Gate 41."
So my family picked up our luggage and carried it over to Gate 41.
Not ten minutes later the public address v oice told us that Flight 570
would in fact be boarding from Gate 35. So again we gathered our
carry-on luggage and returned to the original gate.
Just as we were settling down, the public address voice spoke "Thank You
for participating in Delta's physical fitness program."
