No matter how much you try to explain how RAH isn't a good idea, people won't listen to you.
Right now, Endeavor is $160,000 over your first 3 years, while RAH is at $110,000. If you can't grasp how large $50,000 is, what else can be used to explain about the differences.
When Pinnacle (Endeavor) went bankrupt, Delta took over the DCI Pinnacle portion and dumped the United flying (Colgan), which United had to scramble and use RAH to staff, which has since dumped it. Delta decided they needed to pay more at Pinnacle to keep it going, but didn't want to fund the United side. RAH is likely going to go through a similar transformation soon, where Delta will pull away from RAH in a way United pulled away from Pinnacle. Delta will probably shift the flying to Endeavor and Mainline Delta (in a way that the Colgan flying shifted to RAH from Pinnacle/Colgan), while UAL, AA, or both UAL and AA foot the bill to make RAH sustainable(if they choose to).
So to recap, 3 years of pay at $160,000 at a growing company with good attrition or 3 years of pay at $110,000 at a company likely to shrink further with standard attrition.
