Per diem is a reimbursement plain and simple. It's not compensation, nor does the IRS count it as compensation. Period.
Point me to one other airline advertising that or medical in their compensation figures on their ads. Endeavor advertises $50K first year and that's ONLY the 75 hour min plus the bonus. No bogus per diem or Heath insurance in that figure. I haven't seen one other airline be disingenuous in their ads like Republic.
Get back to me when Endeavor starts advertising $70,000 first year "compensation" because that's exactly what it is, using "Republic math"
