Terminal 2E at Charles de Gaulle-Roissy has recently expanded to add a series of “M” gates, and the new building is impressive.
There are several coffee shops, lounge chairs, shops and even a little (free!) museum with exhibits borrowed from Paris’s well-known museums, to give you a taste of what you can see in town.
These gates are primarily used by Air France.
The bad news? You can’t control when you’ll be at the 2E-M gates (versus 2E-K, 2E-L or 2G). It’s just luck of the draw!
