Both NY and MIA are roughly 20-25% of the size of ORD and DFW. That’s good when a base is junior, bad when it is senior. MIA is relatively senior. But either way, the ability to drive to work, especially if you are within one hour, and being on reserve, priceless.
Either way you choose, you will be commuting to ORD or DFW for a while, but the 145 is the most likely way to get the drive to work.
