SpiceJet working to expand fleet
Last week, SpiceJet said that it is working to expand its fleet to about 60 aircraft through a combination of wet and damp leases, along with bringing grounded planes back into service in phases.

The carrier aims to more than double its capacity, targeting 220 crore Available Seat Kilometres by Winter 2026.
