Also available is an optional new four-piece airport mat set (GJAPS008). Made of heavy-duty polyurethane, the sections feature a runway, taxiways, gate markings and designated terminal space. Plus, the mats are reversible and give collectors the opportunity to double the size of their layouts with a parallel second runway! And, by adding a second new GeminiJets terminal, the gates and jet bridges increase to a total of 44 positions – making an impressive airport diorama twice as impressive!
