Interesting...
She was a flight safety risk.
By what standard did you measure this, are you qualified to make that comment, and do you know the Qantas requirements for a FA to safely do her job?
She would not have been able to get out of an overwing emergency exit
How did you arrive at that conclusion? Were you at her last EP's session, are you privy to her records from Qantas HR?
The above are genuine questions. Or are you just making uninformed and speculative assumptions?
I have my doubts about her being able to negotiate the aisles and would definitely have been a flight safety risk had she attempted to waddle from the galley to an exit thereby blocking pax from getting out in an emergency)
Really? For all you know she could be a professional power lifter.
And what message does it give to the paying customer?
A different question entirely; one I can answer as an Australian. The paying customer couldn't care less. They aren't going to choose Virgin/J*/Tiger instead of Qantas because of a large Flight Attendant.
