My DFW-FCO flight scheduled for next month has been departing recently out of Terminal A (of course today it's from D but that can change). It's really disappointing because I want to check out the new D lounge. I'm thinking of checking in and going through security at Term D, visit the lounge then take the Skylink over to terminal A. Is there going to be a problem with this from an airport security standpoint? Not checking any bags and I'm taking an Uber to the airport so parking is not a problem. Thanks!
