Teacher: Now, understand the problem? Solve this instance: I am required to pick someone up at the CDG airport. I live in Gif-sur-Yvette in ile-de-France and can get to RER stop "CDG 1" (that caters to CDG terminal 1). I read that I would need to take the CDGval to terminal 1.

However, the map of terminal 1 level and CDGval level doesn't quite tell me how to get from the CDGval stop for T1 to the arrivals of T1. There appear to be several "levels" to T1.

Also Is there a particular gate at T1 that arriving passengers exit through? My passenger will be arriving on United airlines.
