Excerpts from the South China Morning Post - 11 May 2006:
"There was hot air coming out of the vents," she said. "The captain announced that it might be because the engine was off and that it should cool down once we were up in the air."
The plane, carrying 222 passengers, took off 22 minutes late.
"After two hours in the air, I felt really claustrophobic and had an anxiety attack. I told my husband I felt like I couldn't breathe," frequent flier Mrs Hira said. "An air hostess noticed and they were fanning me, getting me napkins with ice every 10 to 15 minutes to calm me down.
"My driver in economy class told me the situation was even worse there, with at least two people lying down in the walkway."
A Cathay Pacific spokeswoman said a valve in one of the plane's air-conditioning systems was faulty.
However, Mrs Hira asked why passengers were made to put up with such difficult conditions for four hours when the problem was apparent from the outset.
"If your parts are faulty, you should not take off to begin with. If they thought it would get better but it didn't, it shouldn't have taken them so long to decide to turn around - it was a 12-hour flight."
Anyone can fly, only the best Soar.
