For a self-transfer between Mumbai Airport (BOM) and Navi Mumbai International Airport (NMI), consider around six hours between domestic flights and seven to eight hours when an international flight is involved. These are cautious planning recommendations, not official minimum connection times or guarantees. An overnight stop is worth considering before an expensive international departure booked separately.
BOM and NMI are separate airports. You must leave your arrival airport, travel by road and complete departure formalities at the other airport. A short driving estimate does not account for baggage collection, immigration, taxi pickup, check-in or boarding deadlines.
BOOK A TAXI OR CAR FOR THE TRANSFER. DO NOT EXPECT TO CATCH AN AUTO BETWEEN THE TWO AIRPORTS.
The most important calculation: Work backwards from the time you need to reach the next airport—not from the flight’s takeoff time. If your international flight departs at 8 p.m. and your airline asks you to arrive three hours early, your target is the correct departure terminal by 5 p.m.
Suggested buffers are editorial planning advice for travellers arranging their own transfer. Check your airline’s current deadlines and any written connection arrangements.

How Much Time Should You Allow Between BOM and NMI Flights?
The table below refers to the gap between your first flight’s scheduled arrival and your next flight’s scheduled departure. It assumes that you are arranging the road transfer yourself.
| Connection type | Suggested booking buffer | Main considerations |
|---|---|---|
| Domestic arrival → domestic departure | Around 6 hours | Airport exit, baggage collection, taxi pickup, road journey and fresh check-in |
| Domestic arrival → international departure | Around 7–8 hours | International reporting time, document checks, security and departure immigration |
| International arrival → domestic departure | Around 7–8 hours | Arrival immigration, baggage, customs and the cross-city transfer |
| International arrival → international departure | Consider an overnight stop | Entry into India, arrival formalities, ground transfer and another international departure |
No buffer guarantees a successful connection. An extended flight delay, severe traffic disruption or heavy rain can consume several hours. Allow more time when travelling with children, older relatives, mobility assistance or substantial luggage.
If both flights use BOM, this table does not apply. Read our Mumbai Airport transit guide for connections within the existing airport.
Is Four or Five Hours Enough Between Mumbai and Navi Mumbai Airports?
It may work when everything runs smoothly, but it should not be advertised as a safe minimum. A four- or five-hour gap can shrink quickly once your first flight arrives late or your bags take longer to appear.
For example, a five-hour gap before an international departure gives you only two hours to leave the arrival airport and complete the road transfer if you aim to reach the departure airport three hours early. That leaves little room for baggage collection and taxi pickup, let alone a delayed flight.
Before booking, consider the consequences of missing the next flight. Saving a small amount on an earlier domestic connection may not justify the cost of replacing a long-haul ticket.
What about a two- or three-hour gap?
Do not deliberately book a two- or three-hour self-transfer between BOM and NMI. These airports are not neighbouring terminals. Even a relatively quick drive would leave very little time for everything before and after it.
What Must Your Connection Time Cover?
A useful planning formula is:
Connection gap = arrival processing + vehicle pickup + road journey + departure-airport reporting time + disruption buffer.
| Stage | What to include |
|---|---|
| Leaving the aircraft | Reaching the stand, doors opening, deplaning and walking or taking a bus to arrivals |
| Arrival formalities | Baggage collection; immigration and customs where applicable |
| Finding your vehicle | Reaching the pickup zone, locating the driver and loading luggage |
| Driving between airports | Traffic, route changes, weather and airport approach roads |
| Departure formalities | Terminal entry, document checks, bag drop, security, immigration where applicable and walking to the gate |
| Contingency | Late arrival, slow baggage delivery, a cancelled taxi booking or an unexpected queue |
For an initial plan, setting aside approximately two hours for the road portion is a cautious starting allowance—not a measured average or an upper limit. Increase it when live traffic or weather indicates a longer journey.
Do not assume you will be in a taxi 20 minutes after arrival. Equally, do not assume every international arrival can complete immigration, baggage collection and customs within one extra hour.

Domestic Flight to NMI, International Flight From BOM
This is a connection where generous planning matters. After arriving at NMI, you need to collect any checked bags, find your car, travel to the correct BOM terminal and complete international departure procedures.
Air India’s Mumbai departure guidance recommends arriving three to four hours before international flights. Follow your own airline’s instructions if they differ.
Example: noon arrival at NMI and 8 p.m. departure from BOM
The following is an illustrative plan, not a prediction of actual journey times:
- Noon: Scheduled arrival at NMI.
- 1 p.m.: Working target to have collected baggage and met the driver.
- 3 p.m.: Working arrival estimate at BOM after allowing two hours on the road.
- 5 p.m.: Airport reporting target if the airline requires arrival three hours before departure.
- 8 p.m.: Scheduled international departure.
This plan creates roughly two hours of contingency before the 5 p.m. reporting target. A two-hour inbound delay could consume that margin completely. If the airline asks you to arrive four hours early, the margin is smaller.
For a separately booked international ticket that would be expensive to replace, arriving the previous day is worth considering.
International Flight to BOM, Domestic Flight From NMI
After arriving internationally at BOM, allow time for immigration, baggage collection and customs before meeting your driver. Then travel to NMI and complete the domestic airline’s departure process.
International arrival time is not the time you will be ready to leave the airport. Queues, baggage delivery and any additional checks can change the timing substantially.
A seven- to eight-hour scheduled gap is a cautious starting point for this self-transfer. Consider a later flight or an overnight stay if you are travelling with family, expect additional formalities or cannot afford to miss the onward service.
Also check your luggage allowance before booking. The domestic flight may allow less baggage than the international ticket. Our international-to-domestic baggage guide explains this common problem.
Check-in Closing Time Is Not Your Airport Arrival Target
There are separate deadlines for check-in, bag drop and boarding. Reaching the terminal before takeoff does not mean you can still board.
For example, IndiGo’s published requirements state that check-in counters close 60 minutes before domestic departures and 75 minutes before international departures. Passengers must also meet the specified boarding-gate deadline.
These are closure times, not recommended times to arrive outside the building. Your journey through terminal entry, queues and security must fit before the relevant deadlines.
Does online check-in make a short connection safe?
No. Online check-in may save one step, but it does not move your luggage between airports or remove security, document checks and gate deadlines. If you have checked bags, you must still meet the bag-drop cutoff.
See our airport arrival-time guide for planning the final part of your journey.
Use a Taxi or Car for a Flight Connection
DO NOT EXPECT TO CATCH AN AUTO-RICKSHAW FOR A BOM–NMI AIRPORT TRANSFER. Arrange a taxi or car for the complete journey, with sufficient luggage space and the exact departure terminal entered as the destination.
NMIA’s official transport page lists taxi services and Uber Auto for local connections. A local auto pickup service should not be interpreted as a dependable through service to BOM.
Why we do not recommend local trains for this connection
Local rail is not a direct terminal-to-terminal transfer. You may need road transport at both ends and train changes between suitable services. Not every Harbour Line train serves the station you need.
Platform changes may involve stairs and footbridges. Do not assume working lifts or escalators will be available throughout the journey. Crowded trains, carrying suitcases and keeping valuables secure add further difficulty.
For an airport connection with a deadline, use a direct car. Do not build your itinerary around a future metro link or an unconfirmed shuttle service.
Before meeting the driver
- Confirm BOM or NMI and the correct terminal.
- Share the flight number and agree how arrival delays will be handled.
- Check pickup instructions, waiting charges and luggage capacity.
- Keep the driver’s contact details and booking confirmation accessible.
If you are arriving from abroad, arrange connectivity in advance. Read how to get internet after landing in India.
Separate Tickets, Connection Protection and Checked Bags
Are both flights protected if they appear in one booking?
Do not assume that one booking reference includes a protected road transfer. Ask the airline or booking agent to confirm who arranges transport, who pays for it and what happens if an inbound delay causes you to miss the onward flight.
For separate tickets, plan on managing the connection yourself unless written terms explicitly provide protection. Do not assume the second airline will rebook you without charge because another carrier arrived late.
Will your bags move automatically between airports?
Plan to collect and transport your own luggage unless the airline explicitly confirms another arrangement. Ask specifically about the change between BOM and NMI, rather than simply asking whether the bags are “checked through.”
Keep medicines, documents, chargers and other essentials in your cabin bag in case the onward flight needs to be changed.
Do international passengers need permission to enter India?
Yes, a road transfer requires passing through immigration and entering India. The permission needed depends on your nationality and immigration status. Do not assume that an airside transit exemption covers travel between airports.
Check the official Indian visa portal and confirm your documents with the airline before departure. The Ministry of Home Affairs transit guidance distinguishes remaining within the specified airport area from entering India.
When Is an Overnight Connection the Better Choice?
Consider staying overnight when:
- Your onward international flight is on a separate, expensive ticket.
- A missed connection would disrupt a cruise, wedding, tour or important appointment.
- You are travelling with children, older relatives or someone needing assistance.
- The onward flight is the last suitable service of the day.
- Heavy rain or other disruption could make the road journey unpredictable.
- You would otherwise spend the transfer worrying about a narrow margin.
Choose accommodation with the next departure airport in mind. A hotel advertised as “near Mumbai Airport” may be near BOM, even when your next flight departs from NMI.
Where practical, complete the inter-airport journey before your overnight rest. Confirm late check-in and the following day’s airport transport directly with the hotel.
What Should You Do if Your First Flight Is Delayed?
- Recalculate immediately. Compare your expected arrival at the next airport with its reporting and check-in deadlines.
- Contact the onward airline before becoming a no-show. Ask about changing the flight and protecting any remaining sectors.
- Contact the booking agent if it arranged a protected connection. Request instructions in writing.
- Update your driver. Confirm the revised pickup and any waiting charges.
- Keep evidence. Save delay notifications, booking records and relevant receipts.
Do not ask a driver to compensate for a late flight by speeding. Once the timing becomes unrealistic, focus on rebooking rather than trying to recover every minute on the road.
If an airline changes your flight from BOM to NMI, or the reverse, reassess the whole connection before accepting the revised itinerary. Our Mumbai airport flight-change guide explains what to check.
Frequently Asked Questions
Is six hours always enough between BOM and NMI?
No. Six hours is a cautious starting recommendation for a domestic self-transfer, not a guarantee. Severe delays can exceed your available buffer.
Can I allow less time if I have only hand baggage?
You may leave arrivals sooner, but the road journey, terminal entry, security and boarding deadlines remain. Hand baggage alone does not make a tight connection dependable.
Is the transfer quicker late at night?
Traffic may be lighter, but pickup delays, roadworks and airport queues remain possible. Use live information and retain a buffer rather than assuming an overnight transfer will be fast.
Does the same advice apply from NMI to BOM and from BOM to NMI?
Yes. The planning method is the same, but arrival formalities, the departure terminal, traffic direction and airline deadlines can change the time required.
Can I wait overnight inside the departure terminal?
Do not assume unrestricted overnight entry. Terminal access and check-in availability depend on your flight and airport arrangements. Check our guide to arriving early at Indian airports before relying on the terminal as your overnight waiting place.
What is the safest way to avoid an inter-airport connection?
Choose flights that arrive and depart from the same airport, confirming the code on each sector. If that is not practical, book a generous gap or stay overnight near the onward departure airport.
