IndiGo runs tight group-booking desks for its Delhi–Singapore and Delhi–Bangkok corridors. If you’re moving 10 or more people, the published retail fares you see online are not the price you should be paying. Here’s what the process actually looks like.
TL;DR: What is IndiGo’s group booking process for SEA routes?
IndiGo offers a dedicated group booking desk for parties of 10 or more passengers. For the Delhi–Singapore (DEL–SIN) and Delhi–Bangkok (DEL–BKK) routes, you raise a group fare request via groups@goindigo.in or through IndiGo’s official group booking portal, and the airline comes back with a negotiated block rate — typically better than retail if you’re booking well ahead and your travel dates are flexible. The exact discount off the retail price isn’t published, but groups travelling 21+ days out and willing to pay a deposit upfront tend to see the most competitive quotes. Verify current group pricing directly at goindigo.in before committing.
Why group fares exist — and why IndiGo’s SEA routes are worth targeting
Airlines don’t love empty seats. Group fares are essentially airlines pre-selling blocks of seats to a single buyer at a slightly lower yield in exchange for guaranteed revenue. For IndiGo, the DEL–SIN and DEL–Bangkok routes are among its highest-demand international corridors — connecting India’s capital to two Southeast Asia hubs where load factors are routinely high.
That’s actually good news if you’re organising a group. IndiGo has enough seat inventory on these routes that its group desk can actually work with you, unlike some thin routes where the airline simply won’t negotiate. I’ve seen corporate travel desks in Delhi pull reasonable quotes on the SIN route for 15-pax blocks travelling in shoulder months, whereas the same group trying to book October Diwali peak got stonewalled. Timing matters more than you might expect.
For a quick scan of current publicly available IndiGo fares to Singapore and Bangkok before you call the group desk, FlightGPT’s AI flight search can show you the retail landscape so you know whether the group quote you receive is actually a deal.
The 10-pax minimum: what counts and what doesn’t
IndiGo’s group threshold is 10 passengers on the same flight and date. A few things people often get wrong:
- Infants don’t count. A party of 9 adults and 3 lap infants is still 9 adults for group-fare purposes.
- All pax must travel together. You can’t combine two unrelated bookings of 5 people each and call it a group after the fact.
- Return legs can be booked separately. If your group is returning on different dates, IndiGo typically handles each direction as a separate group request — which is fine, but requires two separate quotations.
- Codeshare itineraries don’t qualify. If the actual operating carrier on your itinerary is a partner airline, IndiGo’s own group desk won’t price it. Stick to IndiGo-operated flights.
Once you confirm you meet the threshold, the process kicks off with a quote request. Budget 24–48 hours for IndiGo’s group desk to respond during weekdays; longer over weekends.
How to raise a group booking request: step by step
- Compile your passenger list. IndiGo will want full names (as on passports), nationalities, and passport numbers at the quotation stage — not just headcount. Have this ready before you email.
- Email groups@goindigo.in with your route (e.g., DEL–SIN), travel date range, number of passengers, and whether you need a return block. Subject line: “Group Booking Request — DEL–SIN — [Date] — [Pax Count] Pax”.
- Wait for the quote. IndiGo will send a fare quote with a deposit deadline — typically a percentage of the total fare to hold the block, with the balance due closer to departure. The deposit is usually non-refundable if you cancel, so don’t lock in until your group is confirmed.
- Review the conditions. Group fares on these routes often have restricted name-change policies — one or two name changes might be permitted (sometimes for a fee), but don’t count on swapping half the group two weeks before travel.
- Pay the deposit and get PNRs. Once the deposit clears, IndiGo issues individual PNRs for each passenger. Check that the names match passports exactly at this stage.
If you’re a registered travel agent, IndiGo’s agent portal or your GDS (Amadeus, Galileo, Sabre) may have a faster group-request workflow — worth checking with your agency account manager.
Seat-block deposits, payment timelines, and cancellation traps
The deposit structure IndiGo uses for group blocks isn’t publicly stated in fine print — it’s negotiated case by case. In practice, what I’ve seen reported by agents is a deposit in the range of 20–30% of the total fare within a few days of the quote, with the balance typically due somewhere between 30 and 60 days before departure. Treat those as rough guidance, not gospel — IndiGo’s group desk will tell you the exact timeline in the quote email.
The trap: if your group falls below the 10-pax minimum after you’ve paid a deposit (someone drops out), you may lose the group rate and the deposit converts to a regular booking at a different fare class. Pin down your group size before you commit money.
Cancellations on group blocks follow the group-fare rules stated in your quote, which are typically stricter than standard IndiGo cancellation policy. Don’t assume the usual retail-ticket refund rules apply. Ask the group desk explicitly what the cancellation penalty is before signing off.
Baggage, meals, and other inclusions on IndiGo group blocks
IndiGo is a low-cost carrier, so group blocks on DEL–SIN and DEL–BKK typically include checked-baggage as an add-on, not automatically. However, the group quote can sometimes bundle a checked bag allowance — ask for it explicitly, because adding baggage after the fact for 15 people adds up fast.
Meals on IndiGo’s international routes are not included by default. You can pre-order meals in bulk through the group desk at the quotation stage, which is usually cheaper than individual in-flight purchases. For a group of 15 travelling DEL–SIN, that meal pre-order conversation is worth having upfront.
Seat selection: group blocks usually allow seat selection, but IndiGo may not guarantee all seats together unless you request adjacent seating at the time of booking. If your group absolutely needs to sit together (families with kids, seniors), mention it explicitly in the initial email.
Agent commission and B2B group booking via FlightGPT Partner
If you’re a travel agent handling this booking for a client, IndiGo’s group fares are typically structured as net fares — you receive a negotiated rate and build your service fee on top. Commission structures vary by agent agreement and aren’t something IndiGo publishes openly.
For agents who want a consolidated view of group-fare options across multiple carriers for the DEL–SIN and DEL–BKK corridors, FlightGPT Partner (the B2B portal at agent.flightgpt.in) is worth checking alongside your GDS for retail fare comparison. Group blocks will still need to be negotiated directly with IndiGo’s group desk, but having a live retail-fare benchmark helps you validate whether the group quote is actually competitive.

Bottom line: when IndiGo group fares actually make sense on SEA routes
Group blocks on DEL–SIN and DEL–BKK make most sense for:
- Corporate offsite travel of 10–25 pax with fixed dates and a clear trip purpose (IndiGo’s group desk responds well to corporate bookings).
- University student groups travelling for exchange programs or competitions.
- Wedding destination groups where the bride and groom are locking in travel for both families simultaneously.
They make less sense for loosely assembled friend groups where individual drop-outs are likely, or for last-minute travel (the group desk isn’t going to find you a group block 5 days before travel).
Start the process at least 60–90 days out for leisure travel, 30–45 days for corporate trips with firm commitment. And always use FlightGPT to check retail fares first so you know your baseline before the group desk quote lands in your inbox.
Frequently asked questions
What is the minimum group size for IndiGo group booking on Delhi–Singapore?
IndiGo’s standard minimum is 10 passengers on the same flight and date. Infants (lap babies) don’t count toward this threshold. You can confirm the exact current minimum by emailing groups@goindigo.in or calling IndiGo’s group desk.
How far in advance should I request a group fare for Delhi–Bangkok?
Ideally 60–90 days before your travel date for leisure groups, and 30–45 days for corporate bookings with committed headcount. Requesting too close to departure (less than 3 weeks) often results in poor availability or no group block at all on high-demand routes like DEL–BKK.
Does IndiGo group fare include checked baggage for international routes?
Not automatically on most low-cost group blocks. IndiGo’s group desk can often include a checked-bag allowance if you ask at the quotation stage — it’s usually cheaper bundled than added individually for each passenger later. Always ask explicitly when reviewing the group quote.
Can I change names on an IndiGo group booking after the block is confirmed?
Group-fare name-change rules are stricter than retail. Typically one or two name changes per block may be permitted (often for a fee), but this is specified in the group quote document IndiGo sends. Assume name changes are limited and get clarity before paying the deposit.
Is there a group discount for Delhi–Singapore on IndiGo versus retail fares?
Yes, group blocks typically carry a discount versus the equivalent retail fare class at the time of booking, but the exact percentage isn’t published and varies by travel date, demand, and how far in advance you book. The benefit tends to be stronger in shoulder months (April–May, September–October) rather than peak Diwali or December travel. Verify the current group rate by requesting a quote directly from IndiGo.
Can I book IndiGo group fares through a travel agent?
Yes. Registered IATA agents can raise group fare requests through their GDS or through IndiGo’s agent portal. The group quote process is the same, but agents typically receive a net fare structure with their service margin built in.
