What to watch

  • September and October DGCA domestic passenger data, especially recovery around festive and holiday travel.
  • Monthly airline load factors, seat capacity growth, cancellations and on-time performance.
  • Domestic airfare indices and evidence of broad promotional pricing.
  • IndiGo versus Air India Group market-share changes and route additions or withdrawals.
  • Airport operator disclosures on non-aeronautical revenue, retail sales per passenger and F&B spend.
  • Hotel occupancy, airline booking trends and online travel-platform gross booking commentary.
  • Reduce near-term volume assumptions for airport retailers, food courts, lounge operators and airport cab partners; retain caution on non-aeronautical revenue forecasts.
  • Track whether traffic weakness is concentrated in specific airlines, regions or leisure routes before revising broader consumer-demand assumptions.
  • Watch for airline fare promotions and capacity cuts: discounting would support traveller volumes but pressure airline profitability and ancillary monetization.
  • Assess Air India Group's share gains for changes in airport terminal mix, loyalty-program spend and premium-travel capture.
  • Separate passenger-volume risk from spend-per-passenger trends; premiumization can offset part of the footfall decline at metro hubs.
