Cayman Airways (KX, Grand Cayman Island) has said it will not sell any of its three B737-300s before 2020 as the aircraft are required to cover for the grounded B737-8s, the Cayman News Service has reported.

"Despite the ongoing delay, CAL still intends to retire and sell its 737-300 jet fleet, though no aircraft are expected to be sold before 2020," a spokesperson said.

Originally, the carrier hoped to sell all three B737 Classics by the end of 2019. It intended to replace them with B737-8s. It took delivery of the first B737 MAX in late November 2018 and the second on March 7, 2019. The second unit, VP-CIX (msn 63561), did not enter into revenue service before the type's grounding.

The airline was originally due to take the third MAX 8 in September 2019 and the fourth in September 2020. All four units are dry-leased from Air Lease Corporation.

Cayman Airways' B737-300s are 24.6 years old on average and are owned by the airline, the ch-aviation fleets advanced module shows.

Besides the three Boeing twinjets, Cayman Airways also operates two DHC-6-300s and two Saab 340B(Plus) aircraft through its subsidiary Cayman Airways Express.
