Go First (Mumbai International) has put around twelve of its fifty-two A320-200Ns in long-term storage as it awaits delayed redeliveries of upgraded Pratt & Whitney PW1100G engines, The Economic Times daily has reported.

The Indian low-cost carrier, formerly known as GoAir, sent the powerplants to the manufacturer in January 2022, hoping to receive spare engines on an interim basis. The upgrades themselves were due to take around five months. Sources indicated that the airline did not receive the spare engines, while the redeliveries of the upgraded units were delayed and are currently expected by mid-July.

The ch-aviation fleets module shows that Go First operates fifty-two A320-200Ns and five A320-200s. Only the A320neo generation aircraft are affected by the PW1100G engine issues.

Rival IndiGo Airlines (6E, Delhi International) completed the upgrade of all of its PW1100G engines by the end of August 2020, although it has since changed the engine supplier for its newly delivered A320neo Family aircraft to CFM International. The Indian Directorate General of Civil Aviation (DGCA) barred all operations of the non-upgraded PW1100G powerplants as of September 1, 2020, although the deadline was later extended for Go First.
