I am looking at several flight options, one takes me from Dulles to CDG, where I have 1:45 minutes to change planes, the other is through Amsterdam where I have 1:30 miinutes. Return through Paris I have 1:25 minutes or return through JFK where I have close to 3 hours. I seem to remember CDG was trains and buses to change planes. My Mother is traveling with me with a wheelchair, which helps cut the lines but adds to the stress. Advice?
