If your d/h is MEM-ATL-CDG for example and you want to cnx the MEM-ATL leg and keep the ATL-CDG leg you can and the GT will be waiting for you in CDG when you arrive. The catch is two fold, when you deviate only deviate on the MEM-ATL leg (first error most crew members make is they deviate on both legs) now FOX will cancel both legs(who knows why) so now you need to call Corp Travel and rebook ATL-CDG on the exact same flight that is on the pairing. Your GT in CDG is tied to the second leg. You can confirm this by looking at the Summary Format of your pairing and it will show exactly what legs you are deviating on. Same holds true for coming back to the states if you have a two leg CDG-AMS-MEM. Keep the CDG-AMS, deviate on AMS-MEM, rebook pairing CDG-AMS leg and the GT will stay. I have been doing this ever since we went to FOX and it works everytime.
