Susan Boyle 'Upset' On Australia Flight - Comments and Message Board

I wonder why she was tired and upset. Within 6 days she flew from the UK to NY to LA to OZ and did numerous interviews and performances at each stop. That's a lot of hours on a plane, 4 different time zones and a lot of stress.I wonder how her team would have held up if they didn't get to sit on their butts the whole time and watch her work.
