Airline strategy begins with a question that aircraft orders and route announcements cannot answer: what allows a carrier to earn a return after paying for its fleet, people, distribution and disruptions?

Willy Boulter explains how a low-cost carrier can reconsider its product and aircraft mix without abandoning cost discipline. Jay Shabat places those decisions in the wider setting of consolidation, pricing and India's evolving airline structure. Ameya Joshi's scrutiny of SpiceJet adds the distinction between a fresh funding round and a sustainable operating recovery.
