I don't think a good idea to have installed and active 2 KORD in the sim, a duplicate jetways will be.
You shouldn't have to do this, since the DD Chicago airports product also includes KMDW and KPWK, you don't have to lose them in P3D4, just do as follows:
- Start the DD installer, and de-select KORD, this will remove DD KORD and leave the other two in place. And yes, it will also disable the DD SODE Jetways file.
