IndiGo, India's largest carrier, is considering advancing its aircraft rental agreements to as early as February next year.
The airline plans to lease Boeing 787s from Norwegian carrier Norse Atlantic to expand its international routes.
IndiGo had already ordered Airbus A350-900 and A321XLR aircraft for long-range operations, but plans to introduce them earlier than expected.
The Directorate General of Civil Aviation has revised norms allowing airlines to rent planes for up to 18 months to help overcome capacity constraints.
