They’ll start with some of the little stuff like ensuring that English language standards are utilized throughout the airport. Sure they’ve got the right to use French, but plenty of other airports within Europe and elsewhere are quick to post plenty of signs in multiple languages to improve traveler comfort. More stuff includes spending a whole bunch of euros on a new addition to Terminal 2E. Construction should get underway this summer, and things should be finalized and opened to the public around 2015.
New shops, restaurants, and other opportunities to get screwed over by the unfavorable exchange rate are also scheduled to appear over the next few years as well. There are even plans to send some of the airport employees off to some sort of charm school with the intention that they'll learn a little bit more about what passengers are looking for when they’re on the move.
Sounds like a good start to us, but it’s going to take plenty of work and improvement to overcome the airport and its bad reputation. Unfortunately the plans have nothing to do with installing some of those baguette vending machines, but that might be a good start if you ask us.
