Our flight from TUS to ORD departs at 12:30 p.m. A taxi will pick us up by 10 a.m., so we will have plenty of time to check in at the airport. We are estimated to arrive at ORD at 5:35 p.m. and our flight to Paris is estimated to depart at 6:10 p.m.! We expect to have 35 minutes or less to get on the flight to Paris! Fingers crossed that all goes as planned by the airlines and we make it. The flight from ORD to Paris De Gaulle is 8 hours, so we will have time to rest and practice our French. Voila! Bon voyage!
