So I landed in terminal 8 and flew out of terminal 2. After I picked up my bag the drop off was a one world alliance drop off. I asked the guy and he said he wasn't sure if the bag would make it so I took it with me to terminal 2. There I asked delta and they said they interline with RJ so I could have left it there but that with a drop off only an hr before departure there was a possibility it wouldn't make it
