Transat A.T. has signed two agreements for the seasonal leasing of Boeing 737 narrow-body aircraft, to be provided during the winter months by Europe Airpost, a French airline that is a subsidiary of the ASL Aviation group, as well as Czech carrier Travel Service Airlines. The agreements cover the leasing of two B737-700s and two B737-800s with respective capacities of 148 and 189 seats. The aircraft will be operated by Air Transat on its Mexico and Caribbean Sun destinations routes. This announcement marks the completion of Transat’s narrow-body internalization plan for winter 2014–2015, begun in July 2013. With this strategy implemented, Transat boasts a flexible fleet comprising Boeing 737s, along with Airbus A310s and A330s, with configuration to be adjusted according to seasonal tourism market fluctuations. In 2013 Transat announced the signing of a long-term agreement with U.S.-based International Lease Finance Corporation (ILFC) for four permanent B737-800s, as well as an agreement with carrier Transavi France for seasonal leasing of B737-800s. In 2015, the Air Transat fleet will consist of 21 wide-body aircraft (nine A310s and 12 A330s with capacities of 250 and 342 respectively), 4 narrow-body B737-800s flown in the summer season, and a total of 12 narrow-body aircraft operated in winter (ten B737-800s and two B737-700s).
