Flight Nurses Staffing in the ED

Do you get paid more as a flight nurse than a staff nurse? Our problem is that we don't get paid much more than staff nurses and we have a lot more training and new more expensive uniforms. Our hospital doesn't help us with uniform expense either.

How many flights per year does your team fly? Do you float in the ED or take full patient load.

I am asking because our team is writing a proposal for a raise and it is hard to do research on this topic because hospitals don't exactly advertise what their nurses do on down time.
