Traveled today on another airline from FRA T2 where my flight departed from C gates. If you are traveling on Qatar Airways and holding Sapphire and Emerald status, do not clear security and passport control at gates C13-C20 if you want to use the JAL Lounge or the Cathay Pacific Lounge. Instead, take the shuttle/AirTrain to Terminal 2 after checking-in and clear passport over there as you were going to travel from gates D and E as an N/S passenger. Then go to the lounge and after using the lounge follow signs for D13-D20, clear security over there and you would be at the same lobby with gates C14-C16 where Qatar Airways flights depart from without any other SkyTrain/Transfer bus.
This is the method that I luckily discovered.
