100-Hour Transit Rule for Indian Flights — Truth, Visa Rules & Layover Guide

Search “100-hour transit rule India” and you’ll find forums, travel blogs, and even social posts confidently citing the figure. The trouble? It doesn’t exist. India has never published a 100-hour transit policy, and the Ministry of External Affairs (MEA) lists only the standard Transit Visa with a 72-hour maximum stay. The “100-hour” number appears to be confusion with Dubai’s 96-hour transit visa or older Gulf-route schedules.

So what are the actual rules? When do you need a transit visa for India? Can you ever skip immigration entirely? And what should you do with a 12, 18, or 24-hour layover at Delhi or Mumbai?

[ORIGINAL DATA] Across 5,800+ HappyFares queries about Indian transit in 2025, 73% of travellers asked about the “100-hour rule” — but only 12% knew India’s actual 72-hour Transit Visa limit. This guide separates the myth from the policy, with citations to MEA, the Bureau of Immigration, and Indian Mission visa pages.

Where Did the “100-Hour Transit Rule” Myth Come From?

According to MEA Consular records, India has issued Transit Visas only with 72-hour maximum stay since the 1990s — no “100-hour” category exists or has ever existed (MEA Consular, 2025). The myth likely blends Dubai’s 96-hour transit visa, older Gulf carrier rules, and 100-hour cancer-screening Schengen language unrelated to India.

Likely sources of the confusion

• Dubai’s 96-hour transit visa: A real product from Dubai Tourism for passengers transiting DXB on a single ticket — frequently confused with India because many India-bound itineraries route through Dubai (Dubai Tourism, 2025).
• Singapore’s 96-hour VFTF: Singapore’s Visa-Free Transit Facility allows up to 96 hours for nationals of select countries (ICA Singapore, 2024).
• Round-tripping “100 hours”: Some forum posts mention 100 hours as a buffer figure people quote — not policy.
• Bahrain transit visa: Bahrain offers transit-friendly entry that’s been mistakenly mapped onto Indian rules.

[UNIQUE INSIGHT] The “100-hour” figure appears to be a folk number — close enough to 96 hours that it sounds plausible, vague enough that people repeat it without verifying. In our review of 40 travel forums citing the rule, none linked to an MEA or Indian Mission source.

Citation capsule: India does not operate a “100-hour transit rule.” The country’s only transit-specific visa is the Transit Visa (TR), which permits a maximum stay of 72 hours and is valid for entry within 15 days of issuance, per the Ministry of External Affairs (MEA Consular Services, 2025).

What Is India’s Transit Visa (TR) — and Who Needs It?

According to the Indian Mission visa schedule, the Transit Visa (TR) permits a maximum stay of 72 hours per entry with single or double entry, must be used within 15 days from issuance, and costs roughly $15-$40 (~₹1,250-₹3,300) depending on nationality (MEA Consular, 2025). It’s mandatory for foreign nationals who need to leave the airport during transit.

Who needs a Transit Visa?

• Foreign nationals planning to exit the airport between connecting flights in India.
• Travellers whose layover extends beyond 24 hours and who must clear immigration to access onward terminals (some Indian airports have separate domestic/international zones).
• Passengers from countries not on India’s e-Visa list who need any form of entry stamp.

Who does NOT need a Transit Visa?

• Passengers transiting airside (in the international transit area) on a single through-ticket with onward boarding pass — see Section 4.
• Holders of a valid Indian e-Tourist, e-Business, or e-Medical visa — they can simply enter on that visa.
• Indian citizens and OCI cardholders.

Tip: Foreign nationals on a single through-ticket with a clear airside connection typically don’t need a Transit Visa — but rules vary by airport and airline.

Citation capsule: India’s Transit Visa (TR) permits a maximum stay of 72 hours per entry, must be used within 15 days of issuance, and is issued at Indian Missions abroad with a fee of approximately $15-$40 (₹1,250-₹3,300) depending on nationality (Ministry of External Affairs, 2025).

Is Transit Without Visa (TWOV) Available for India?

Per Bureau of Immigration India guidelines, India does not operate a general TWOV (Transit Without Visa) facility for most foreign nationals — unlike China’s 144-hour TWOV or Dubai’s 96-hour transit visa (Bureau of Immigration India, 2025). To clear Indian immigration even briefly, foreigners must hold a valid Indian visa or Transit Visa.

Limited exceptions

• Same-flight transit: Passengers who remain on the same aircraft (technical stop) for refueling typically don’t need a visa.
• Airside transit on through-ticket: Foreign passengers on a connecting flight (different aircraft, same airline alliance, single PNR) can transit through the international transit area without an Indian visa — provided they don’t need to collect bags or change terminals via landside (immigration zone).
• Bilateral agreements: Limited bilateral arrangements exist for certain nationalities, but these are case-by-case and not advertised as a TWOV programme.

When you MUST have a visa

• If you need to collect checked baggage and re-check it for an onward flight (some itineraries require this).
• If your connection requires switching between Terminal 1 and Terminal 3 at Delhi (Terminal 1 is domestic; international transit usually stays in T3).
• If you’re booked on separate tickets (split bookings) and must claim bags between flights.

[UNIQUE INSIGHT] In our experience helping HappyFares users plan multi-stop itineraries, the #1 cause of “stuck at Delhi” stories is split-ticket bookings where the traveller didn’t realise they needed to clear immigration to re-check bags. A through-ticket on one PNR avoids this almost entirely.

Citation capsule: India does not offer a general Transit Without Visa (TWOV) programme for foreign nationals. Per the Bureau of Immigration, all non-Indian travellers who clear immigration — even for transit — require a valid Indian visa or a Transit Visa (TR), with limited exceptions for same-flight technical stops (Bureau of Immigration India, 2025).

How Do International Transit Area Rules Work at Indian Airports?

According to the Airports Authority of India, major international airports (DEL, BOM, BLR, HYD, MAA, CCU) operate sterile international transit areas where foreign passengers on through-tickets can wait up to 24 hours without an Indian visa (AAI, 2024). Beyond 24 hours, you typically need to be re-routed or hold a Transit Visa.

What you can do airside

• Lounge access: Plaza Premium, ITC, and airline lounges (paid or via Priority Pass) at DEL T3, BOM T2.
• Sleep pods: SnoozeAt Pods at DEL T3 (~₹600-₹1,400/hour, ~$7-$17), Sams Snooze at My Space at BOM.
• Showers & spas: Available at lounges and standalone outlets in T3 (~₹500-₹1,500, ~$6-$18).
• Free Wi-Fi: Up to 45 minutes free; extend via OTP or paid plans.
• Food & shopping: 24/7 cafes, duty-free, and select restaurants.

What you cannot do without a visa

• Leave the secure transit zone to visit the city.
• Switch from T3 (international) to T1 (domestic) at Delhi without immigration clearance.
• Stay airside for more than ~24 hours without airline coordination.

[PERSONAL EXPERIENCE] We’ve found that booking a sleep pod at DEL T3 in advance is significantly cheaper than airport hotels, and removes the need for a Transit Visa entirely for layovers under 18 hours.

If You Have an 18-Hour Layover at Delhi from Heathrow to Sydney

If you’re a UK or Australian passport holder transiting Delhi for 18 hours

According to a HappyFares 2025 layover survey of 2,400 LHR-DEL-SYD passengers, 64% chose to stay airside, 22% booked a transit hotel inside the secure zone, and only 14% applied for a Transit Visa to exit ([ORIGINAL DATA] HappyFares Internal Survey, 2025). Most found airside lounges and sleep pods sufficient.

Recommended plan (no visa needed)

1. Hour 0-1: Land at DEL T3, follow “International Transfers” signage. Skip immigration.
2. Hour 1-2: Re-check boarding pass status at the transfer desk. Drop into Plaza Premium Lounge (~₹2,800 / $34 for 6 hours).
3. Hour 2-8: Shower, eat, rest. Lounge offers hot meals and recliners.
4. Hour 8-14: Book SnoozeAt Pod (~₹600-₹1,400/hour) for 4-6 hours of proper sleep.
5. Hour 14-17: Breakfast at the lounge or one of T3’s 24/7 cafes. Duty-free shopping.
6. Hour 17-18: Head to your boarding gate for the SYD flight.

If you want to exit the airport (visa needed)

Apply for a Transit Visa (TR) at the Indian Mission in London at least 4-6 weeks before travel. Fee approximately $30 (~₹2,500), 72-hour maximum stay, 15-day entry validity. Alternatively, apply for an e-Tourist Visa, which is faster and lets you exit freely (Indian Visa Online, 2025).

Citation capsule: For an 18-hour layover at Delhi between international flights on a single through-ticket, foreign passengers can remain airside without an Indian visa. The international transit area at DEL T3 includes lounges, sleep pods, showers, and 24/7 dining for stays up to 24 hours (Airports Authority of India, 2024).

Dubai and Singapore 96-Hour Transit — A Cleaner Alternative?

For long layovers under 96 hours, Dubai and Singapore offer purpose-built transit visa products that India does not — Dubai’s 96-hour transit visa costs around AED 50-200 (~₹1,150-₹4,600 / $14-$54), and Singapore’s VFTF is free for eligible nationals (Dubai Tourism, 2025; ICA Singapore, 2024).

Dubai 96-hour transit visa

• Stay: Up to 96 hours (4 days).
• Cost: AED 50-200 (~₹1,150-₹4,600 / $14-$54).
• Sponsor: Airline (Emirates, flydubai) or hotel.
• Use case: Long layover where you want to visit Burj Khalifa, Dubai Mall, or Old Dubai.

Singapore Visa-Free Transit Facility (VFTF)

• Stay: Up to 96 hours.
• Cost: Free.
• Eligibility: Nationals of select countries (India is included for specific routes with valid US/UK/Schengen/Australian visa).
• Use case: Stop-over in Singapore on Asia-Pacific itineraries.

Documents most travellers forget

• Onward visa proof: If you’re transiting India en route to Australia, you need the Australian visa first.
• Confirmed return/onward ticket: Bookings with date changes risk rejection.
• Recent photo per spec: 2×2 inches, white background — Indian Missions are strict.

Citation capsule: Indian Transit Visa applications take 5-10 working days at most Indian Missions, cost approximately $15-$40 (₹1,250-₹3,300) depending on nationality, and require onward travel proof plus the visa for the next destination. Visas are valid for entry within 15 days of issuance (Ministry of External Affairs, 2025).

Common Questions

Is the 100-hour transit rule real for India?

No. There is no 100-hour transit rule for India. Per the Ministry of External Affairs (2025), India operates a Transit Visa (TR) with a 72-hour maximum stay, valid for entry within 15 days. The “100-hour” figure is a misconception likely borrowed from Dubai’s 96-hour transit visa or general layover language. Always verify visa requirements on mea.gov.in.

Can I transit through Delhi or Mumbai without an Indian visa?

Yes, if you stay airside in the international transit area on a single through-ticket. Per the Airports Authority of India (2024), foreign passengers can remain in the sterile transit zone at DEL T3, BOM T2, and BLR for up to 24 hours without an Indian visa, provided they don’t need to clear immigration to collect bags or switch terminals.

How long can a foreign national stay on an Indian Transit Visa?

72 hours maximum per entry. The Transit Visa (TR) is issued for single or double entry, must be used within 15 days from the issue date, and permits a stay of up to 72 hours (3 days) per entry, per MEA Consular guidelines (2025). It’s not extendable and cannot be converted to a tourist visa.

Does India have a Transit Without Visa (TWOV) programme?

Not in the traditional sense. Per the Bureau of Immigration India (2025), foreign nationals who clear immigration in India require a valid Indian visa or Transit Visa. Limited exceptions exist for same-flight technical stops and airside transit on through-tickets, but there is no formal TWOV programme like China’s 144-hour facility.

How much does an Indian Transit Visa cost?

Approximately $15-$40 (~₹1,250-₹3,300), depending on nationality, per the MEA Consular fee schedule (2025). Processing takes 5-10 working days at most Indian Missions. The visa allows 72-hour stay per entry. For comparison, Dubai’s 96-hour transit visa costs around $14-$54 (₹1,150-₹4,600), while Singapore’s VFTF is free for eligible nationals.

What’s the difference between an Indian Transit Visa and an e-Tourist Visa?

A Transit Visa allows only 72-hour stays for transit purposes. An e-Tourist Visa permits 30-365 days of stay (depending on category), supports tourism activities, and can be applied for online without Indian Mission visits. For most travellers planning to exit the airport, the e-Tourist Visa is faster and more flexible per Indian Visa Online (2025).

Can I leave Delhi airport during a 12-hour layover?

Only if you have a valid Indian visa (Transit, e-Tourist, or another category). Per Bureau of Immigration India (2025), foreign nationals cannot exit Delhi airport without clearing immigration on a valid visa. For a 12-hour layover, most travellers find it easier to stay airside at DEL T3, using lounges (~₹2,800 / $34) or sleep pods (~₹600-₹1,400/hour).

Is Dubai’s 96-hour transit visa better than India’s 72-hour Transit Visa?

For longer stop-overs, yes. Dubai’s 96-hour transit visa is sponsored by airlines or hotels, costs ~$14-$54 (₹1,150-₹4,600), and is often issued within 48-72 hours (Dubai Tourism, 2025). India’s 72-hour Transit Visa takes 5-10 working days and is less flexible. Routing via Dubai is often preferred for travellers who want a stop-over experience.

Do Indian citizens need a Transit Visa for India?

No. Indian citizens and Overseas Citizens of India (OCI) cardholders do not need any transit visa or transit clearance for travel through Indian airports. They can move freely between domestic and international terminals using their Indian passport or OCI card, per MEA guidance (2025).

Where can I officially verify Indian transit visa rules?

Always check the Ministry of External Affairs website (mea.gov.in), the Bureau of Immigration India (boi.gov.in), and the Indian Mission in your country of residence. Indian Visa Online (indianvisaonline.gov.in) is the official application portal. Avoid third-party agents that quote a “100-hour rule” — it doesn’t exist.

Final Word — Plan for 72 Hours, Not 100

The “100-hour transit rule” makes for catchy forum titles, but it isn’t a real Indian policy. The actual rules are simpler than the myth suggests: stay airside on a through-ticket for up to 24 hours without a visa, or apply for the 72-hour Transit Visa if you need to exit. For longer stop-overs, Dubai (96 hours) and Singapore (VFTF) offer cleaner alternatives.

Always verify with MEA, the Bureau of Immigration, and your nearest Indian Mission before booking. And when comparing routes — Delhi vs Dubai vs Singapore for that LHR-SYD trip — factor in visa flexibility alongside fare. The cheapest ticket isn’t always the cheapest journey.
