I am booked to arrive into CDG Terminal 2D on Air France from Strasbourg, and I have another flight with Iberia 2 hours later from Terminal 1. Do you think this is possible? Is there enough time to collect baggage and check-in for the MAD flight? Are there regular buses between the two terminals and where can one find them?

THanks very much in advance.
PS I have searched all over the CDG website to know avail, including in French ('correspondence').
