Ifly, I did leave & for the exact reasons you mentioned.
Many have left, many are in the process of leaving, the attrition rate is huge, because guys are doing exactly what you say you would do.
But if you want to sign up for a $36,000 bond and 3 years to realise everything that has been posted is true then good luck.
And I didn't say you can't survive on an FZ salary. You can survive, but many come to Dubai to save for a better future, a family on an FO salary struggles to saves any meaningful amount.
