Air India’s group desk quotes for the Delhi–Mumbai sector typically come in 8–15% below the lowest published economy fare available on that booking date — but the gap narrows sharply as departure approaches. Here’s how the saving actually works, when it’s worth the paperwork, and when you should just buy 10 individual tickets instead.
TL;DR — the short answer
Air India’s group fares on Delhi–Mumbai (DEL–BOM) typically run 8–15% below the lowest published economy fare available on the day you request the quote, for groups of 10 or more passengers. The further out you book, the wider the gap — at 60+ days out it can touch 15%, while at 2–3 weeks it often shrinks to 5–8% or disappears entirely on high-demand dates. Group fares also come with a deposit structure and a different cancellation policy, so the saving isn’t free money. Read on before you assume it’s always the right call.
How Air India’s group booking process actually works
Air India’s group desk operates separately from the public booking engine at airindia.com. To get a group quote you either email the group desk directly (the email address is on Air India’s website under ‘Group Travel’) or go through a travel agent who has a group-booking contract with Air India. Most corporate travel managers and IATA-accredited agents can pull group quotes from Air India’s GDS connection or via the dedicated group portal.
The minimum group size for Air India domestic groups is typically 10 passengers on the same booking, travelling on the same flight and date. Once you submit a request with the route, date, and passenger count, the group desk sends back a ‘group fare offer’ — a net rate that is held for a limited time (often 24–72 hours). You then have to confirm and pay a deposit to lock the seats. The balance is usually due around 30–45 days before departure, though this varies by contract and season. Verify the current deposit and payment schedule directly with Air India’s group desk before committing — these terms do change.
One important nuance: the group fare is not a seat-by-seat fare in the same inventory buckets as public fares. Air India allocates a dedicated block of seats for group fares out of the group inventory, which is why group rates can remain stable even when public fares are spiking due to last-minute demand.
What discount benchmarks actually look like on DEL–BOM
Delhi–Mumbai is India’s busiest trunk route with dozens of daily departures across Air India, IndiGo, and Akasa. Because public fares on this route are highly dynamic and competition is intense, the group saving benchmark is more variable here than on thinner routes.
Based on fare comparisons I’ve tracked and quotes that travel agent contacts have shared (without breaching commercial confidentiality), here’s the rough picture as of early 2026:
- 60+ days out: Group fares often come in around 12–18% below the lowest public economy fare on the same departure date. On high-demand dates (long weekends, festival dates like Diwali week), the group inventory may be limited and the saving narrower.
- 30–60 days out: The gap typically compresses to around 8–12%. Public fares start rising but group fares don’t always rise proportionally — the group desk is working from a pre-allocated block.
- Under 30 days: This is where it gets unpredictable. If the flight has open group inventory, you might still see 5–8% off. If the flight is filling fast, public fares could have spiked enough that the group desk’s base rate is no longer meaningfully cheaper. In some cases, buying individual tickets via a fare alert (use FlightGPT to track fare drops on the route) can beat the group quote.
The honest caveat: these are illustrative ranges, not guarantees. Your actual quote will depend on the specific departure, day of week, season, and how Air India’s revenue management has priced that flight. Always get the quote, then compare it against the current public fare before committing.
What’s included (and not included) in the group fare
A group fare on Air India domestic typically includes checked baggage (usually 15–25 kg per passenger depending on the fare class quoted — confirm in the offer letter) and a meal on flights where catering is standard. What it does not usually include:
- Seat selection: Groups are often bulk-assigned seats. If specific seating matters (a corporate team that needs to work together, or a school group needing adjacent rows), ask the group desk explicitly and get it in writing. There may be an additional charge for pre-assigned block seating.
- Name changes: Group bookings typically allow a limited number of name changes (often 1–2 per every 10 passengers) up to a certain number of days before departure. After that, name changes may carry a fee. This matters if your group composition is likely to shift — a wedding group where a couple drops out, for example.
- Air India miles or Flying Returns credit: Group fare tickets are often in restricted booking classes that do not earn Flying Returns miles, or earn at a lower accrual rate. If your passengers are frequent flyers who care about miles, factor this in.
When group fares genuinely make sense vs buying individual tickets
Group fares are worth the paperwork when:
- Your group is large (20+ passengers), the travel date is fixed, and you’re booking well in advance (60+ days). The saving on a 20-person group trip at even 10% off a ₹6,000 one-way fare is around ₹12,000 — meaningful, and probably enough to cover the agent’s facilitation fee.
- You need a block of confirmed seats on the same flight and aren’t willing to risk the group being split across multiple departures if you try to buy individually during a high-demand period.
- The deposit structure works for your cash flow. Group fares let you lock seats with a partial deposit and pay the balance later — useful for corporate travel managers handling budget approvals.
Group fares are often NOT worth it when:
- Your group is exactly 10–12 people and you’re booking a route with deep competition like DEL–BOM. IndiGo’s regular promotional fares on this route are frequently very sharp. Use FlightGPT to compare individual fares across carriers before assuming the group desk will beat them.
- The departure is under 3 weeks away. At that point, public fares on Air India may have already spiked, but the group desk’s base rate might not reflect that premium — or the group inventory might be exhausted.
- Name flexibility is a high priority. Individual tickets — even at a slightly higher base fare — give each passenger their own PNR with standard cancellation/change options. One dropped group member on a group PNR can complicate refunds for everyone.

Working with a travel agent vs. going direct to Air India
You can request a group quote directly from Air India’s group desk, but most corporate and group travel in India is still handled through IATA-accredited travel agents. There are a few practical reasons for this:
Agents with group-booking contracts often have direct relationships with the airline’s group desk team and can turn around quotes faster, negotiate seat allocation, and manage the deposit payment on your behalf. They may also be able to ‘hold’ group space informally for a day or two while you get internal approvals — something the airline’s public-facing process doesn’t always accommodate.
The agent earns through the net vs. published fare spread (the airline pays them a net rate and they charge you the group rate or a service fee on top — the exact commercial structure varies and agents don’t usually disclose the specific markup). For large groups, the agent’s facilitation is usually worth it. For a 10–12 person group, shop around — some agents add a per-head service fee that eats into the saving. If you’re a travel agent yourself managing client groups, FlightGPT Partner provides a B2B portal for group fare queries and booking management.
Bottom line: get the quote, then compare
The Air India group fare saving on Delhi–Mumbai is real but not automatic. At 60+ days out and 15+ passengers, you will almost certainly save meaningfully over buying individual tickets at the public fare. At under 30 days, or on dates when IndiGo has already run sale fares, the math may not work in the group fare’s favour. The discipline is to get the group quote AND check the current public fare on the same route and date before you commit. FlightGPT makes that comparison quick.

Frequently asked questions
What is the minimum group size for Air India domestic group fares?
Air India’s domestic group minimum is typically 10 passengers travelling on the same flight and date. Some routes or contract types may have a higher minimum. Verify the current threshold directly with Air India’s group desk or through an IATA-accredited agent, as these terms are set per fare cycle.
How much deposit do you need to pay to hold Air India group seats?
Air India’s group desk typically requires a deposit of around 25–33% of the total group fare at the time of confirmation, with the balance due roughly 30–45 days before departure. These terms vary by contract and season. Get the specific deposit schedule in writing in the group fare offer letter before you commit.
Can you earn Flying Returns miles on Air India group fares?
Group fare tickets are typically issued in restricted booking classes that either do not earn Flying Returns miles or earn at a lower accrual rate (often 25–50% of the base mileage vs. a publicly booked economy fare). If miles matter to your passengers, check the booking class in the group offer letter and verify the accrual rate on Air India’s Flying Returns programme page.
What happens if one person in the group can’t travel?
On most Air India domestic group fares, a limited number of name changes are permitted before departure (often around 1–2 per every 10 passengers, within a specific window). Outright cancellation of one passenger from a group PNR may incur a per-passenger cancellation fee, and the deposit treatment depends on the specific fare rules. This is covered in more detail in our article on <a href='/blog/group-flight-one-pax-cancels-india-airline-partial-refund'>partial refunds when one group passenger cancels</a>.
Is it cheaper to book 10 individual IndiGo tickets or one Air India group booking on DEL–BOM?
It depends entirely on the date, season, and how far in advance you’re booking. On days when IndiGo is running promotional fares (which happen regularly on this trunk route), individual IndiGo tickets can be cheaper than an Air India group quote. Use <a href='/'>FlightGPT</a> to check current fares across carriers, then request the Air India group quote and compare. Don’t assume the group fare wins automatically.
Do travel agents charge extra for arranging Air India group bookings?
Commercial arrangements vary. Most agents earn through the net-vs-published fare spread on group bookings, meaning their margin is built into the group rate rather than charged separately. Some agents also charge a per-head service or facilitation fee on top, particularly for smaller groups. Ask for the all-in per-person cost and compare it to the public fare before signing off.
