On A Charted Flight From O'Hare International Airport to Malaga, Spain, my family and I flew on an Air Plus Comet Airbus a310. It was very cramped onboard, but the service was excellent.
The Airport In Malaga was very neat. It was fairly large, with several flights coming in and out every hour, but not as busy as O'Hare! The airport itself was outfitted with many gates and concourses, and several baggage claims.
O'Hare's international terminal is awesome. It has a bunch of artwork all over and giant windows which allow you to see your plane from the gate.
Both airports were set up nice and easy to get around.
