Couldn't have said it better myself metro man.
Last year my spend was $ 30K with QF for myself and my staff.
This year that spend is with Virgin for domestic and Air Asia for international.
You already stated the reason. At least with these I get what I paid for.
If your so called full service airline is deliberately busting weight limits, skimping on maintenance, training, and customer service, and forcing you to check your own baggage, then why not fly a low cost carrier that does none of this ????
