You do not need IATA accreditation to start issuing tickets and earning. Here is exactly how the sub-agent model works in India in 2026 — the documents, the B2B portal login, the wallet, and how you add your own markup.
Quick answer
You do not need IATA accreditation to start working as a travel sub-agent in India. The fastest, lowest-cost route in 2026 is to register on a B2B booking portal (a consolidator or aggregator that already holds the airline relationships), top up an agency wallet, and start issuing tickets under their inventory. You earn by adding your own markup on top of the net fares the portal shows you. To look professional you mainly need a PAN, a GST registration, some proof of business, and ideally a free IATA TIDS code — none of which require the expensive IATA agent accreditation.
What 'sub-agent without IATA' actually means
Let's clear up the confusion first, because the trade throws around three different things as if they're the same.
- IATA accreditation — the full agency accreditation that gives you direct BSP (Billing and Settlement Plan) ticketing power. It needs financial guarantees, a bank guarantee, premises checks and a meaningful deposit. Most new agents in India never start here, and they don't need to.
- TIDS — IATA's free identifier for non-ticketing intermediaries. It is not the same as accreditation. It just gives you a recognised IATA-issued code so suppliers can attribute your bookings. As of 2026, IATA confirms TIDS is free of charge.
- Sub-agent — you, booking through someone else's accreditation. The consolidator or B2B portal holds the BSP/airline relationship; you ride on top of it.
So a 'sub-agent without IATA' is simply an agent who issues tickets and packages using a partner's inventory and ticketing power, while keeping the customer relationship — and the markup — for themselves. This is how the large majority of small and mid-size agencies in India actually operate. You'll see it called sub-agent, B2B agent, retail agent or 'agent under consolidator'. Same idea.
If you're weighing this against going fully accredited, our companion guides on IATA vs TIDS and how to get IATA accreditation lay out the trade-offs.
Why the sub-agent model makes sense in 2026
The honest reason most people go this route: cash and speed. Full accreditation ties up capital in deposits and guarantees, and the approval cycle is slow. The sub-agent model flips that.
| Factor | Sub-agent via B2B portal | Full IATA agent |
|---|---|---|
| Upfront cost | Low — mostly your wallet float | High — deposit + bank guarantee |
| Time to go live | Days, sometimes same-day | Weeks to months |
| Ticketing power | Through the portal's accreditation | Direct via BSP |
| Inventory reach | Many airlines + series + group, one login | What you contract directly |
| Best for | New agents, sub-agents, side businesses | High-volume, established agencies |
The other big shift is inventory. A single good B2B portal now aggregates regular airline fares plus series fares, group fares and fixed departures across carriers like IndiGo, Air India, Akasa and SpiceJet. Ten years ago you'd have chased each of those separately. Now you can reach them from one screen — which is exactly the gap FlightGPT Partner is built to fill.
What you actually need to get started
You can keep this list short. None of it requires IATA accreditation.
- PAN — yours if you're a sole proprietor, or the firm's PAN if you've registered a business. Non-negotiable for invoicing and TDS.
- GST registration — get registered if you're crossing the threshold or just to look credible and claim/issue proper tax invoices. Many portals expect a GSTIN before they hand you net fares. Confirm your exact threshold and obligations with your CA.
- Proof of business — shop establishment certificate, Udyam/MSME registration, a partnership deed or company incorporation, or even a registered sole-proprietorship with a current bank account. Most B2B portals just want to KYC you, not audit you.
- A business bank account — for wallet top-ups, refunds and settlement. Keep it separate from your personal account from day one.
- A free TIDS code — optional but recommended. It's IATA-issued, costs nothing, and adds legitimacy when you talk to suppliers or print documents. See our TIDS registration guide.
That's genuinely most of it. The heavier compliance — escrow, bank guarantees, premises — belongs to the accredited partner whose rails you're using.
How to register as a sub-agent on a B2B portal — step by step
The flow is similar across portals. Here's the typical sequence.
- 1. Pick your channel. Decide whether you'll work through a traditional consolidator, a large B2B aggregator, or a portal like FlightGPT Partner. Compare a few — we break this down in our best B2B portal guide and a head-to-head comparison.
- 2. Submit KYC. Upload PAN, GST certificate, business proof and a cancelled cheque or bank letter. Activation is often quick once documents check out.
- 3. Fund the wallet. Most B2B portals run on advance/prepaid credit. You load money in; bookings debit from it. More on this below and in our wallet and credit guide.
- 4. Set your markup rules. Decide your default commission/markup so the customer-facing price already includes your margin.
- 5. Issue your first ticket. Search, hold or instant-issue, collect from the customer, and the PNR/ticket comes through the portal's accreditation. Our walkthrough on issuing a flight ticket covers the mechanics.
The whole point: you skip the slow accreditation queue and start transacting almost immediately, while still issuing real, valid airline tickets.
How the wallet, credit and money flow works
This is the part new sub-agents misjudge most, so go in clear-eyed. Almost every B2B portal in India runs on a prepaid agency wallet rather than open credit. You deposit an advance into your agency account on the portal; every booking instantly debits that balance. Run out, and bookings simply stop until you top up.
Why portals do it this way: airline tickets settle fast and refunds are messy, so they don't want to carry your risk. For you, the wallet model is actually a feature — it forces discipline, keeps a clean ledger, and means no month-end surprise invoice. A good wallet shows you a running balance, a transaction-by-transaction ledger, and refunds credited back automatically.
A few practical habits:
- Keep a buffer above your busiest single-day volume so a group booking doesn't get rejected mid-transaction.
- Reconcile your wallet ledger against your own bookings weekly — catch any failed-but-debited or refund-pending entries early.
- Collect from the customer before you issue, especially on non-refundable net fares. Your margin is thin; a no-show client can wipe out several tickets' worth of profit.
Some portals later extend short-term credit lines once you've built a track record, but assume prepaid to begin with.
How you make money: markup, commission and the tax reality
Your earning is the spread. The portal shows you a net fare (or wholesale fare); you add your markup; the customer pays the sum. The difference is yours. Read our explainer on net vs published fares and how to add markup in a B2B portal for the mechanics, including how to set per-route or per-airline rules instead of pricing every ticket by hand.
Now the tax part, and please verify this with your own CA because rules shift:
- GST on your earning. As of 2026, an air travel agent typically charges 18% GST on their commission/earning, not on the full fare. The trade commonly uses a deemed value of 5% of the basic fare for domestic and 10% for international to compute that commission base. This is a long-standing convention — confirm the current position with CBIC or your CA before you build it into your pricing.
- TCS on overseas tour packages. From 1 April 2026, TCS on overseas tour packages is a flat 2%, after the earlier threshold slabs were removed in the Budget. Again, treat this as 'as of Budget 2026, confirm with your CA' — it's the kind of number that gets tweaked.
For the full picture, see our deep dive on GST and TCS on air tickets. The headline for a new sub-agent: keep clean invoices, charge GST on your margin (not the full ticket), and don't guess on tax — a wrong assumption here eats your thin spread fast.
Getting airline, series and group inventory without IATA
Here's the question everyone asks: 'If I'm not IATA, how do I even get fares to sell?' Three ways, all of which work without your own accreditation.
- Through a consolidator. Consolidators buy allotments and net fares from airlines and resell to sub-agents. You get consolidator fares and international net fares without holding BSP yourself.
- Through a B2B aggregator/portal. The platform holds the accreditation and APIs into multiple airlines, then passes through net pricing to registered agents. One login, many carriers.
- Through series and group blocks. Series and fixed-departure inventory is contracted in bulk and resold seat-by-seat — perfect for a sub-agent, because you sell from a block without any airline contract of your own. See series vs group vs FIT to understand the differences.
You can also pull fares programmatically once you scale — our flight booking API guide covers that. And to compare price quality, it's worth understanding the airline-direct vs aggregator trade-off. If you want to sanity-check live fares on specific sectors while you evaluate partners, you can browse public route pages and airline IndiGo fare types, Air India fare types, Akasa fare types and SpiceJet fare types on FlightGPT.
How FlightGPT Partner helps
If you want the sub-agent path with the least friction, FlightGPT Partner is one strong option to look at. It's FlightGPT's B2B portal, and the pitch is simple: one login that aggregates series fares, group fares, fixed departures and wholesale/net fares across IndiGo, Air India, Akasa and SpiceJet — so you don't juggle a separate login per airline.
What that means for a new sub-agent in practice:
- One wallet, not five. A single agency wallet with a live balance and a clean ledger, instead of separate float in every airline's portal.
- Markup built in. Set your commission/markup so customer-facing prices already include your margin.
- GST invoicing. Proper tax invoices out of the box, which matters once you're charging GST on your earning.
- White-label options. Put your own brand in front of customers if you want to look like a full-fledged agency from day one.
To be straight with you: it's not the only way to do this. Established consolidators and the big aggregators all work, and you should compare a couple before committing your wallet float. But for someone who wants series + group + net fares across the major carriers behind a single, modern login — without chasing IATA accreditation first — it's a genuinely good fit. Start by reading the FlightGPT blog cluster, then create a partner account and load a small test float before you go big.
Common mistakes new sub-agents make
A few traps that cost real money in the first six months:
- Issuing before collecting. On non-refundable net and series fares, a backed-out customer is your loss, not the portal's. Collect first.
- Pricing without tax clarity. Forgetting that GST applies to your earning, or mishandling TCS on overseas packages, quietly erodes margin. Lock this down with your CA.
- Treating one portal as gospel. Fares and inventory vary. Keep a primary portal but check a second on big bookings.
- Sloppy name entry. A misspelled passenger name can mean a costly correction or reissue. Read our guide on name change and spelling correction before you need it, and know your cancellation and refund handling cold.
- No buffer in the wallet. Running dry mid-season kills bookings you've already promised customers.
Avoid those and the model is forgiving. You learn the trade on someone else's accreditation, build volume, and only consider your own IATA accreditation or a fuller agency setup once the numbers justify it.
Frequently asked questions
Can I legally issue flight tickets in India without IATA accreditation?
Yes. As a sub-agent you issue tickets through a consolidator or B2B portal that holds the IATA accreditation and BSP/airline relationships. The tickets are real and valid; the accreditation simply sits with your partner, not you. The vast majority of small and mid-size agents in India work exactly this way.
Is TIDS the same as IATA accreditation, and do I need it?
No, they're different. TIDS is a free IATA-issued identifier for non-ticketing intermediaries — it gives you a recognised code but no direct ticketing power. Accreditation is the heavier, paid programme with deposits and guarantees. You don't strictly need TIDS to start as a sub-agent, but as of 2026 it's free and adds credibility with suppliers, so it's worth getting.
Do I need GST registration to become a sub-agent?
Most B2B portals expect a GSTIN before giving you net fares, and you'll want it to issue proper tax invoices. As of 2026, an air travel agent typically charges 18% GST on their commission/earning rather than the full fare, with the trade commonly using a deemed value of 5% of basic fare (domestic) or 10% (international). Confirm your registration threshold and the current treatment with CBIC or your CA.
How does the agency wallet work and how much should I load?
Most Indian B2B portals run on a prepaid wallet: you deposit an advance, and each booking debits it instantly. There's no fixed minimum that fits everyone — load enough to comfortably cover your busiest single day plus a buffer, so a group booking can't get rejected mid-transaction. Reconcile the wallet ledger weekly against your own bookings.
How do I get series and group fares without my own airline contracts?
Series and group inventory is contracted in bulk by consolidators and portals, then resold seat-by-seat to sub-agents. You sell from that block without any airline contract of your own. A portal like FlightGPT Partner aggregates series, group, fixed-departure and net fares across IndiGo, Air India, Akasa and SpiceJet behind one login.
What is the TCS rate on overseas tour packages I sell in 2026?
As of Budget 2026, TCS on overseas tour packages is a flat 2% from 1 April 2026, after the earlier threshold slabs were removed. Treat this as indicative and confirm the current position with your CA, since these rules change and the exact application can depend on your structure.
