• IndiGo marks 20 years with a significant international expansion plan.
• The airline will induct new Airbus A321 XLR and A350 aircraft.
• IndiGo aims to recapture international traffic currently flowing through Gulf hubs.
• The airline focuses on cost leadership and operational efficiency.

IndiGo's expansion may indicate a shift in the airline's strategy to connect the global Indian diaspora, potentially challenging Gulf carriers' dominance in the region. This move could suggest a growing trend of airlines focusing on diaspora traffic and may set a precedent for other carriers to follow, which could impact the competitive landscape of international air travel.
