I'm nervous about my trip back to the states from CDG. I'm taking the TGV from Dijon, France to CDG Term. 2 that gets in at 9:33am. I have a 11:10 United flight to Chicago out of Term. 1. I was planning on checking in online ahead of time and then checking my bags when I got to the airport. Is 90 minutes enough time to get all of this done (including security)? Any help would be appreciated!
