When it has been stated that the youths were going to find help for Father Noel, they cut to an Aer Lingus check in staff member who says 'And that's four tickets to Paraguay'. Aer Lingus offers no direct connections to Paraguay or South America as a whole. To get to South America from Ireland, one has to fly to an airport that offers a direct connection such as London. Also, in 1998, there were no direct flights between Europe and Paraguay, and no European airline had a connection like this. Today, to get to Paraguay from Ireland with the smallest number of transfers, one has to fly to Madrid, Spain, then hop on an Air Europa flight that will take one direct to Asunicon.
