IndiGo & Air India Shift Flights Across Delhi Airport

From October 26 2025, IndiGo and Air India will reshuffle domestic flight operations across Terminals 1, 2 and 3 at Indira Gandhi International Airport (Delhi) to ease congestion, streamline passenger movement and enhance turnaround efficiency—key update for travel-agents, corporates and airline professionals.

Introduction

For travel-industry professionals—from agents and consolidators to corporate planners and airline partners—terminal-changes at major hubs are high-impact events. With Delhi’s IGI Airport reorganising key operations for two of India’s largest carriers from 26 October 2025, it’s essential to update your workflow, client briefings and logistics coordination. This article unpacks what’s changing, why it matters for B2B stakeholders and how you can stay on top of the shift.

What’s Changing: The Terminal Shuffle

IndiGo’s Terminal Allocation

• IndiGo will resume operations from Terminal 2 (T2) from 26 October 2025.

• Under the revised structure:

  • Flights 6E 5000–5999, including all international departures/arrivals, will operate from Terminal 3 (T3).

  • Flights 6E 2000–2999 will operate from Terminal 2 (T2).

  • All other domestic flights (outside 2000-2999 & 5000-5999 series) will continue from Terminal 1 (T1).

Air India’s Terminal Re-assignment

• Air India will move approximately 60 domestic flights (out of about 180 daily domestic departures) to T2 from 26 October.

• The rule-of-thumb: flights with flight-numbers starting ‘1xxx’ (AI1…) will operate from T2.

• Domestic flights of Air India Express (flight numbers starting ‘9…’) will operate from Terminal 1.

• International flights will remain at T3.
  
  

Infrastructure & Operational Context

• T2 has undergone a major upgrade and will start handling roughly 120 domestic flights a day when it opens on 26 October.

• The move helps free up capacity at T3 for expanded international operations and eases crowding at T1 & T3.

Why This Matters for B2B Travel Professionals

1. Streamlined Terminal Logic

With clear flight-number prefixes tied to terminals (e.g., IndiGo 2000-2999 = T2; Air India 1xxx = T2), you can update your agent check-lists, client communication templates and transit instructions effectively. This helps reduce drop-off confusion for walk-in clients, corporate travellers and group bookings.

2. Impact on Ground Logistics & Transfers

• Transfers between terminals may take extra time: While T2 & T3 are ~10-15 minutes’ walk apart, shuttles between T1 & T2/T3 run at ~10-minute intervals.

• For group flight bookings (your core business at Agent Bazar), pre-planning pickup/drop-off, coach meets, baggage-handling is crucial.

• Make sure your airport-meet-and-greet teams are aware of which terminals to operate from after the shift.

3. Booking & Itinerary Accuracy

• Update your internal seat-sold systems and partner portals: for flights on IndiGo and Air India from 26 Oct onwards, ensure the terminal field is refreshed.

• When issuing e-tickets or group documents, embed terminal change info: this reduces the number of terminal-related queries and enhances your professionalism.

• For corporate travellers with tight connections: Advise extra buffer time for terminal change, even if same airline.

4. Client Notifications & Communications

• Use this announcement as an opportunity to engage your B2B clients (corporate travel teams, consolidators). Highlight: “For all IndiGo 6E 2000-2999 = T2 at IGI; Air India 1xxx = T2; Air India Express 9xxx = T1.”

• Consider sending branded advisory emails or push-notifications through your Systeme.io flows to clients booking through your platform.

• Update your CRM tags and triggers: when a new booking enters for Delhi with 6E 2xxx or AI1xxx, trigger a “terminal‐check reminder before departure.

Conclusion & Key Takeaway

For B2B travel professionals working with domestic India group-fares, corporate bookings or airline consolidation, the terminal-reshuffle at Delhi’s IGI Airport from 26 October 2025 is a timely operational signal. By proactively embedding these terminal changes in your booking flows, communications and ground logistics, you strengthen your value-add to partners and clients alike. In a crowded market, demonstrating such operational clarity helps you stand out as a trusted travel-technology solution under the Agent Bazar banner.
