In the articles talking about this change, ADP calls this a "choc de simplification" . This is really laughable as I don't see the simplification at all. If they wanted a simplification, instead of calling terminals 1 to 7 with letters for gate numbers, they should rather name the terminals with letters and use this same letter for gate numbering. I mean Terminal A (gates A1, A2, etc) to G (gates G1, G2, etc).
