Any almost every connection option in the world is more viable from JAX over ATL except for a handful of smaller markets that are hub-exclusive to DTW or MSP.
Agreed but it still warrants more than one daily RJ in the grand scheme of things. we are talking about 14 to one that's just crazy if a customer choses to fly from JAX to anywhere in the Delta network and want's to avoid ATL it's almost impossible. The return from JAX to DTW provides for zero connections A JAX to Asia passenger for instance is in for a double connect because of no connectivity to the Asia flights at DTW. Where as AA and UA can get you to every major Asian city with one stop. I understand that there may be a small amount of O/D from JAX to Asia but for an airline that touts itself as being global AA and UA have better international connection and more 1 stop options than Delta does in their network due to the everything over ATL concept.
DL would prefer a JAX passenger to go to ATL and if they have to double connect in ICN so be it. That's they way its going to be with the imminent DL-KE JV
I'm BOS based - to be honest I could care less about this BOS-JAX add - its already well served by B6 and I'm sure people go through ATL/CLT/. I'm more impressed by DL's additions in BOS-FLL/RSW/PBI. Now if DL bumped those up while having RJ's on DTW then you would have a legitimate concern.
