I have booked air and car rental though Expedia before without problems. I am looking at booking an international ticket which appears will be ticketed by Expedia with Air France mostly flights flown by Delta). Some of the connections are okay unless the airlines would change their schedules which they often do. Once booked if a flight schedule is changed prior to initial departure date, whereas a connecting flight is impossible to make, must I get the schedule changed with Air France or Expedia? Once we are enroute and we miss a connecting flight due to the airline arriving late, do we talk to Air France or Expedia? It would seem to be very cumbersome in this circumstance if changes ahd to be made with Expedia? Has anyone ever experienced either of these situations? Thank you.
