The one aircraft registered with the airline, an ex-Viking Airlines MD-83 based in Athens, is only to be used as a back-up, while the core of Viking Hellas’ operations in the beginning will be operated with Viking Airlines’ Swedish-registered fleet of 737-300s and 737-800s out of Manchester. The airline is in the process of acquiring two A320s, one of which will take over the scheduled operations and the other which will operate charter flights out of Heraklion in Crete.
