Jet Airways has grounded two more aircraft after it failed to pay their lease rentals.

The carrier disclosed the additional groundings on 23 February in a letter to its two stock exchanges. It had previously disclosed that four jets were grounded for non-payment of rentals on 7 February, but none of the six aircraft have been identified, nor the lessors involved.

“The company is actively engaged with all its aircraft lessors and regularly provides them with updates on efforts undertaken by the company to improve its liquidity,” it adds.

It is unclear if the grounded jets will be voluntarily returned to lessors, or if they are subject to repossession orders.

Cirium’s Fleet Analyzer shows that the majority of Jet’s fleet is leased, with GECAS, Aircastle and BOC Aviation among the most exposed lessors.
