it was always wise to yell up the stairs prior to boarding "Is this the Teesside?"
Boarded a Continental Airlines DC-10 at Honolulu for a flight to Aukland, CC made the welcome aboard announcement for a flight to Sydney, all the pax yelled out as one "we're going to Aukland, CC responded you should be on the aircraft on our left. Some delay while things were sorted, we were on the correct aircraft but I was left wondering about the crew.
