The Albanian Airplane is a plane that makes regular flights between Tirana (the capital of Albania) and Springfield.
Adil Hoxha took the flight from Tirana to Springfield as part of his spy mission under the cover of the foreign student exchange program. When he was caught, he was deported from the USA and put on the flight back to Tirana. Adil was exchanged for an American child spy who had been caught in Albania and sent to the USA on the flight's Tirana-to-Springfield leg.
