Iv already said nothing wrong with asking for more $$.
Its the tinfoil hat crowd that rationalizes the holiday pay request as a way to modify and control pilots behaviors.
Its equally laffable to cite 'industry standard' and what out FAs have or dont have.
Comparative envy logic is stock and trade for the crowd you seem to belong to.
Just stand up and say you want more $$. For no other reason than you want it.
Honestly....you will find it very liberating.
