ATL-CDG-BOM Baggage Question
 

My sister is flying to India in a couple days to visit relatives on DL. She will have a week-long stopover in Paris before continuing on to India. As expected, she will be very close to the maximum limit allowed for luggage. I believe it to be 70 pounds for each of her two checked bags.

My concern is regarding her luggage. I'd hate for her to carry the bags around everywhere in the city. Is there a baggage storage service in CDG that would hold her bags for one week? Any idea on potential costs for two bags for 7 days? The worst case scenario is she lugs them around with her in the city but I am hoping to somehow avoid that situation. Does she have any other options?
