Sources checked: 28 October 2026. Confirm the current flight terminal and coach boarding point with the airline and airport staff.
First confirm that the next flight really departs from Terminal 1 at Mumbai’s Chhatrapati Shivaji Maharaj International Airport (BOM). Do not take a coach merely because the next flight is domestic. Air India, for example, lists check-in counters for both domestic and international flights at Terminal 2. This walkthrough is for an international T2 arrival followed by a confirmed T1 departure, not every Mumbai connection. Official source.
1. Confirm the onward flight before leaving the transfer decision point
Our suggestion: use the current booking, flight number, travel date and airline information to confirm the departure airport and terminal. A different airport is not a terminal change. Ask the airline where it will accept your baggage and which counter or bag drop you must use. If the flight remains at T2, obtain that route instead of travelling to T1.
2. Complete arrival formalities and resolve the baggage route
For the normal international-arrival route, follow immigration, baggage reclaim and the applicable customs process before the public onward journey. Mumbai’s arrival guide identifies immigration for international passengers, flight-specific baggage-belt displays and customs channels. If a particular airline programme gives different instructions, get confirmation for the actual booking; a final-city bag tag alone is not enough to invent an exception. Official source.
3. For an eligible IndiGo connection, carry the bags between terminals
IndiGo’s published international-to-domestic instructions require baggage collection and customs at the first port of entry into India. If the departure terminal changes, passengers carry their own baggage and drop it at the departure terminal’s baggage counter. These instructions are scoped to a valid connection sold by IndiGo in one PNR, not a self-created or multi-city connection merely sharing a reference. IndiGo says it does not provide inter-terminal transportation; use the airport operator’s actual service instructions. Official source.
4. Find T2’s coach point: Level 1, Ground Transportation, P4
After the applicable arrival and customs route, follow current signs or ask airport staff for the inter-terminal coach at Terminal 2, Level 1, Ground Transportation Level (P4). The airport’s arrival page identifies that T2 point. AdaniOne additionally describes it as P4 West side. Do not substitute a taxi pickup, airline transfer desk or a departure gate for the coach point. Official source.
5. Confirm the actual coach to T1 before boarding
Mumbai Airport’s transit guide describes a complimentary T1–T2 shuttle for eligible passengers. Keep the onward ticket or boarding pass ready and ask staff to confirm eligibility and the current boarding point. The coach page lists a 24/7 service with departures every 25 minutes; treat this as the published schedule to recheck, not a promise that you wait exactly 25 minutes or reach the next terminal within that time. Official source.
At the T1 end, the airport’s arrival guide places the coach point between Departure Gates 1 and 2. The coach page describes the arrival exit towards Departure Gate 2; these are descriptions of the T1 end, not the T2 pickup. On arrival at T1, follow staff directions for the airline’s actual departures entry and counter. Official source.
6. At T1, follow the onward airline’s baggage and departure route
For the eligible IndiGo connection described above, carry the bags to the departure terminal’s baggage drop counter. Official source.
Our suggestion: follow the onward airline’s confirmed departure route. Collect or validate the next boarding pass if required, complete domestic security and check the current gate. Do not assume a public coach ride is an airside transfer or that it preserves an earlier security clearance. The airline must confirm the applicable check-in, baggage and gate deadlines for your flight.
7. Judge the whole connection, not the coach frequency
Our planning suggestion: include immigration, baggage, customs, walking to P4, waiting, road travel, the T1 counter and security. Ask promptly if a late arrival makes the onward deadlines doubtful. IndiGo’s page warns travellers to account for terminal movement and does not accept liability for passenger delay in that movement. This guide gives no safe minimum, fixed ride time, automatic rebooking or guaranteed free alternative. Official source.
If you need assistance or cannot find the stop
Ask at an airport information point before heading outside or changing levels repeatedly. Mumbai’s transit guide directs passengers to airport helpdesks or information counters and asks travellers needing reduced-mobility assistance to inform the airline in advance. Confirm the handoff and luggage help you actually need; do not assume an escort or accessible vehicle is included without confirmation. Official source.

Quick questions
Does every Mumbai domestic connection need T1?
No. Confirm the actual flight. Air India, for example, lists check-in counters for domestic and international flights at T2.
Where is the coach point for a T2-to-T1 transfer?
Mumbai Airport lists T2 Level 1, Ground Transportation Level (P4). Confirm the current inter-terminal boarding point with staff; the T1 gate descriptions are for the other end.
Does every 25 minutes mean a 25-minute transfer?
No. It is the published departure interval, not a wait guarantee or the complete connection time. Add arrival formalities, walking, road travel and the next departure steps.
