We have changed from Domestic to International in Toronto once (due to plane trouble in Atlanta) and we had a terrible time finding the right gate--had to ask questions twice, and made it just in time. They fed us well on that flight once we made it to the plane, going from Toronto to Vancouver.

Atlanta is easier for us, but as we almost always use that airport, we know our way around. We have found that sometimes everything runs late in Atlanta. Once, it really worked in our favor as we were late getting there due to a thunderstorm and we were one hour late and our plane to Europe was borading. They, Delta, told us we could not make it, but we tried--and the flight was waiting for us in the E concourse, the one that deals with International flights.
