Unless you actually DESIRE to move from MCI, go with Republic. They have a base at MCI and even if you can’t hold it initially (not sure of base seniority at Republic) commuting on company aircraft is always easier. Don’t get me wrong, if you have a burning desire for Detroit, well....better you than me, I guess.
How soon will you actually have the numbers to get hired? If you can apply six months before then they can probably hold the CJO that long.
