What Is Interline Baggage?
Interline baggage is an arrangement between two or more airlines that allows your checked bags to be transferred automatically from one airline's flight to another, all the way to your final destination — without you having to collect them at connection points.
Interline baggage is only possible when:
- Your entire journey is on a single ticket (one booking reference)
- The airlines involved have an interline agreement with each other
- You are not required to clear customs at the connection point (or the airline's policy allows collection and re-check)
Single Ticket vs Separate Tickets — The Critical Difference
- One booking reference for entire journey
- Bags can be checked through to final destination
- If you miss a connection, airline is responsible for rebooking
- Baggage tag shows final destination code
- More passenger protection overall
- Example: Delhi → Mumbai → London on one Air India booking
- Each leg is a separate booking reference
- Must collect bags at each connection
- If you miss one flight, no airline is responsible
- Baggage tag only goes to connection airport
- You re-check as a new passenger at connection
- Example: IndiGo Delhi → Mumbai (Ticket 1) + British Airways Mumbai → London (Ticket 2)
How to Confirm Your Bags Are Checked Through
- At check-in, ask explicitly: "Can my bags be tagged through to [final destination airport]?" Do not assume — always ask.
- Check your baggage tag. The destination airport code printed on the tag tells you where the bag is headed. If it shows your final destination (e.g., LHR), bags are checked through. If it shows your connection city (e.g., BOM), you must collect and re-check.
- Get a baggage receipt for the full journey. Check-in agents should provide a receipt showing the routing and final destination of your bag. Keep this throughout the journey.
- If unsure, confirm with the agent a second time before leaving the check-in counter. Once you walk away, fixing a mis-tagged bag is significantly harder.
Connecting Through India — Customs Rules for Bags
India has specific rules about bags on international connections that affect whether through-checking is possible:
| Connection Type | Clear Indian Immigration? | Must Collect Bags? |
|---|---|---|
| Transit without visa (airside only) | No | No — bags transfer automatically |
| Indian nationals arriving and departing | Yes | Yes — collect, clear customs, re-check |
| Foreign nationals on transit visa | Yes | Yes — collect, clear customs, re-check |
| Domestic to international connection (same airport) | Yes (entering international zone) | Usually yes — re-check with international carrier |
Airline-by-Airline Interline Baggage Agreements
| Airline | Interline Agreements? | Bags Checked Through? | Notes |
|---|---|---|---|
| Air India | ✅ Broad network | Usually yes (single ticket) | Star Alliance member; wide interline network |
| IndiGo | ⚠️ Limited | Some routes only | Has agreements with select international carriers; verify at check-in |
| SpiceJet | ⚠️ Limited | Some routes only | Verify for each itinerary |
| Akasa Air | ⚠️ Growing | Some routes | Newer carrier; expanding interline network |
| Emirates / Etihad / Qatar | ✅ Wide | Usually yes (single ticket) | Strong interline with Air India and select Indian carriers |
| British Airways / Lufthansa | ✅ Wide | Usually yes (single ticket) | Check with Air India for India connections |
What If Bags Are Not Checked Through
If your bags are only tagged to your connection point, here is the process:
- Go to the baggage carousel at your connection airport and collect your bags
- Clear customs if required (entering Indian customs zone or arriving from international)
- Proceed to the check-in counter for your next flight and check your bags again
- Go through security again for the next flight
- Allow sufficient time: The entire process typically takes 60–90 minutes at major Indian airports
Transit Without Visa and Baggage
Many foreign nationals can transit Indian airports without a visa under India's Transit Without Visa (TWOV) facility, particularly at Delhi and Mumbai airports. If you qualify:
Interline vs Non-Interline — What Changes
| Factor | Interline (Single Ticket) | Non-Interline (Separate Tickets) |
|---|---|---|
| Bag collection at connection | Not required (usually) | Required |
| Responsibility if bag is lost | Airline responsible end-to-end | Each airline responsible only for its leg |
| Missed connection protection | Airline must rebook you | No protection — your problem |
| Baggage fees | Usually combined allowance | Each airline charges separately |
| Minimum connection time | Airline manages (usually safer) | You must manage — allow 2–3 hours |
| Cost | Usually higher (single ticket) | Often cheaper (but higher risk) |
Pro Tips: Checking Bags Through on Indian Flights
- Always book on a single ticket when connecting through India. Single-ticket bookings give you interline protection, missed connection protection, and the ability to check bags through. The price premium is usually worth the reduced stress and risk.
- Ask the check-in agent to confirm the bag destination code before walking away. Look at the tag yourself. If it shows your connection city instead of final destination, address it immediately — once you leave the counter it becomes much harder to fix.
- For domestic-to-international connections at the same airport, allow 3+ hours. Even on a single ticket, collecting domestic bags, clearing arrivals, checking in internationally, and clearing security takes at minimum 2 hours at Delhi or Mumbai. Three hours is safer.
- Choose Air India for connections requiring through-checking. Air India's Star Alliance membership and broad interline network makes it the most reliable choice for bags that need to travel across multiple carriers through India.
- Never put valuables in checked baggage that will be transferred between airlines. Even with through-checking, bags change hands multiple times. Electronics, jewellery, medication, and documents should always be in your cabin bag. See: Will Airlines Deliver Lost Luggage in India?
- Put an AirTag in your checked bag. If your through-checked bag is separated at a connection, you can track exactly where it is. This is particularly useful on multi-carrier itineraries where coordination between airlines can be slow. See: Apple AirTag India Baggage Tracking.
- Check Indian customs rules for your connection type before you travel. The collect-and-re-check requirement at Indian customs connections catches many passengers by surprise. Research your specific connection scenario — transit without visa, TWOV, domestic-to-international — well in advance.
- If bags are mishandled on a through-checked itinerary, file the PIR with the final carrier. On interline itineraries, the last carrier is typically responsible for handling the PIR and compensation claim for mishandled baggage. See: Will Airlines Deliver Lost Luggage in India?

Frequently Asked Questions
Can you check bags through to your final destination on Indian connecting flights?
Yes, on a single ticket with an interline agreement. On separate tickets, you must collect and re-check bags at each connection. Always confirm at check-in that your bag tag shows the final destination airport code.
What is interline baggage and how does it work?
Interline baggage allows automatic transfer of checked bags between airlines on a single ticket. Your bags are tagged to the final destination at check-in and collected only there. Requires both an interline agreement and a single booking.
Does IndiGo offer interline baggage on connecting flights?
IndiGo has limited interline agreements. Check at check-in whether through-tagging is available. For broad interline options through India, Air India (Star Alliance) is the more reliable choice.
Can I check bags through on separate tickets?
No. Separate tickets have no interline arrangement. You must collect your bags at each connection, clear customs if applicable, and re-check with the next airline. Allow 2–3 hours for this process.
What happens to bags during customs clearance on connections through India?
If you enter the Indian customs zone (clear immigration), you MUST collect your bags personally and clear customs. Bags cannot pass through Indian customs without you, even on interline itineraries.
Does Air India check bags through to final destination?
Yes. As a Star Alliance member, Air India has broad interline agreements. On single-ticket itineraries with partner airlines, bags are typically checked through to the final destination. Confirm the baggage tag destination at check-in.
What if my bags are not checked through on my connecting flight?
Collect your bags at the connection airport, clear customs if required, re-check with the next airline, and clear security again. Allow at least 2–3 hours for this process at major Indian airports.
How do I know if my bags will be checked through to my final destination?
Ask at check-in: "Can my bags be tagged to [final destination]?" Check your baggage tag — if it shows the final destination airport code, bags are checked through. If it shows your connection city, you must collect and re-check.
