Series fares are one of the best-kept secrets in the Indian travel trade — fixed-departure seat blocks that agents buy in bulk, often months ahead, at rates that are meaningfully below the public fare at time of sale. Here's a practical look at how agents actually secure and manage series allotment in India, with a focus on summer 2026 demand patterns.
TL;DR — what series fares are and why agents care
A series fare (also called a series booking or fixed-departure seat block) is a pre-purchased block of seats on a recurring departure — the same flight, the same day of the week, across multiple consecutive weeks — bought by a travel agent or tour operator well in advance at a fixed rate. The agent takes on inventory risk (they've paid for those seats) in exchange for a rate that's typically below what the public would pay if they booked those seats individually at the time of sale. For summer 2026, routes connecting metros to leisure and pilgrim destinations are seeing high series-fare demand from agents who locked allotment in early 2026.
How series fares actually work in the Indian travel trade
Series fares sit at the intersection of group booking and wholesale inventory. A travel agent or tour operator identifies a route with predictable weekly demand — say, a tour operator running 30-pax Char Dham packages every Saturday throughout the Yatra season — and approaches the airline's group or wholesale desk to negotiate a series allotment.
The mechanics, in rough terms: the agent commits to buying a fixed number of seats on the same flight every week for a specified number of weeks. The airline prices this as a net rate, usually below the public economy fare that will prevail at time of sale. The agent pays for the seats in advance — or on a rolling deposit schedule — and then sells them through to their clients, holiday packages, or sub-agents at their own pricing.
The risk sits entirely with the agent. If the agent's tour packages don't sell, they're left holding pre-paid airline seats. This is why series fare allotment is a domain for established agents with a clear pipeline — not casual bookings. Platforms like FlightGPT Partner help travel agents manage their group and series fare bookings and track inventory across departures.
Series fares are distinct from one-off group bookings (which are a single group on a single date) and from charter flights (which involve leasing the whole aircraft). A series fare uses scheduled airline seats — just pre-committed in bulk across multiple departures.
Which Indian routes have strong series-fare demand in summer 2026?
Summer in India (roughly April through mid-June, and then post-monsoon September) drives predictable travel patterns that make certain routes especially attractive for series allotment. Based on the general demand patterns and what's visible in agent community discussions (including forums like agentbazar.in, where agents discuss trade inventory):
- DEL/BOM to Srinagar (SXR): Kashmir tourism has been consistently strong. Agents running weekly Kashmir tour packages across the summer season (before monsoon hits in earnest) are among the biggest buyers of series allotment on this route. IndiGo, Air India, and Air India Express all operate here. Series fares locked in January–February for the summer season have historically paid off well on this route.
- DEL to Dehradun (DED) / Jolly Grant: The Char Dham Yatra season runs roughly May–June and September–October. Tour operators running Kedarnath, Badrinath, and Yamunotri packages regularly lock series allotment on the Delhi–Dehradun sector for groups travelling to the foothills. It's a short sector but high-demand.
- Metros to Goa (GOI/GOX): Goa sees a summer dip in leisure travel from Indians (most prefer October–March) but a counterintuitive uptick in school group travel and budget package groups. Summer series fares on BOM-GOI and BLR-GOI are typically available at attractive rates because airlines have unsold inventory during the quieter period.
- BOM/DEL to Leh (IXL): The Ladakh season runs June–September. Demand for Leh is intense in the shoulder weeks of June, and series allotment on this route is sought after but relatively scarce because Leh has limited aircraft type compatibility and airport slot constraints.
- DEL to Varanasi (VNS): Pilgrimage travel to Varanasi is year-round but peaks in certain religious calendar windows. Series allotment here suits agents running spiritual tour packages to the Kashi corridor.

How do you actually secure series allotment from IndiGo?
IndiGo is the largest domestic carrier in India by far and is the airline most agents approach first for series allotment. The process roughly works like this:
You approach IndiGo's trade or group desk (not the consumer group desk — the wholesale/trade relationship) with a proposal: the specific flight number, departure day, dates you want, and number of seats per departure. IndiGo evaluates this against their inventory and revenue management forecasts. If the flight has available group/series inventory, they'll quote you a series rate, deposit terms, and a commitment schedule.
The negotiation is usually about the deposit terms (how much up front, what's the rolling payment schedule as departures approach) and the yield to the airline (they won't give you series inventory on a flight that's going to sell out anyway at full public fare — they're not interested in that trade). You have more leverage on off-peak departures, less popular weekday timings, or routes where the airline has inventory risk.
Practically: if you're an independent travel agent trying to access IndiGo series fares for the first time, you'll need an IATA accreditation or a BSP registration, or you'll need to work through an IATA-accredited consolidator who has an existing series fare contract with IndiGo. First-time agents can't just email IndiGo and get a series allotment on a popular route — the airline typically works with agents who have a track record of filling their allotments.
Managing weekly departures: the operational reality
Once you have series allotment, the work isn't done — it's starting. Managing a rolling series allotment across 8–12 weekly departures requires operational discipline that many smaller agents underestimate:
- Name submission deadlines: Airlines require confirmed passenger names for series-fare seats by a set deadline before each departure — often 7–14 days out. Miss the name submission window and you may forfeit flexibility on that departure's seats. This is a recurring task every week for the duration of the series.
- Release of unsold seats: If your packages aren't selling for a particular week's departure, you may have the option to release unsold seats back to the airline's general inventory by a specified deadline. Understand the release window and fees — releasing seats early (within the allowed window) often incurs less penalty than holding unsold seats until close-in. Some series fare contracts allow release at no cost if done 30+ days before departure; others have fees from day one. Read the contract.
- Name changes: Similar to standard group fares, a limited number of free name changes per departure are typically included. Beyond that, fees apply. For tour operators, this comes up constantly — someone's health fails, a passport renewal gets delayed, a school trip has a last-minute dropout.
- Payment cycle: Series fares often involve rolling payments — you may pay for each upcoming departure's batch of seats on a 30-day rolling basis. Cash flow management matters here. If you're an agent building a series-fare business, the working capital requirement is real.
Series fares vs. booking public fares in bulk: the economic logic
The series-fare model only makes sense if the fixed rate you've locked is meaningfully below the public fare your clients would pay when they actually book. On popular summer routes, this spread can be significant — public fares on Delhi-Srinagar in peak June, for example, can spike dramatically once inventory tightens in the weeks before travel. An agent who locked series allotment in January at a flat per-seat rate can sell summer Kashmir tour packages at competitive all-in prices and still make a reasonable margin, even while public fares are double their locked rate.
The risk: if you've committed to 30 seats per week for 10 weeks and your tour packages don't sell, you're sitting on 300 pre-paid seats with varying cancellation fees. The agents who make series fares work have a clear pipeline — a known base of repeat corporate clients, a tied-up school tour calendar, a confirmed package-tour allocation with a consolidator. Pure speculation (buying series allotment without confirmed downstream demand) is how agents lose money on this product.
Compare this model to buying individual public fares close-in: much lower risk per transaction, but you're competing with everyone else for the same inventory at the same rising prices. For operators who can fill the seats, series fares are the better economics. For everyone else, buying at public fares through a well-timed search on FlightGPT or a price-alert channel is the safer route.
What to watch for in the series-fare contract
A few things that trip up less-experienced agents when reading series-fare contracts:
- Seat count commitments: Some contracts require you to take a minimum percentage of your committed seats per departure even if your group is smaller that week. Understand the minimum take-up clause before signing.
- Fare revision clauses: Some series rates have built-in revision triggers — if aviation turbine fuel prices spike beyond a certain threshold, the airline may have the right to revise the series rate. This is more common on international series fares but exists on domestic too.
- Force majeure terms: What happens to your pre-paid seats if the airline cancels the flight? How is the refund processed? Does the contract allow you to shift to a different departure? These are critical for pilgrimage routes (where weather and road conditions can disrupt travel) and for international routes where political or travel advisory changes can affect demand.
If you're new to series fares, get a lawyer or an experienced senior agent to read the allotment contract before you sign. The terms are not standardised across airlines and the implications of getting them wrong are real.

Frequently asked questions
What is a series fare in Indian aviation and who can buy it?
A series fare is a pre-purchased block of seats on the same recurring flight departure (typically the same flight number and weekday) across multiple consecutive weeks, bought by a travel agent or tour operator at a negotiated net rate. It's not available to individual consumers — you need to be an IATA-accredited agent or work through a consolidator with a series-fare contract with the airline.
Which Indian airlines offer series fares to travel agents in 2026?
IndiGo is the primary carrier for series fares on domestic routes in India given their market share and frequency. Air India and Air India Express also offer series/block allotment, particularly on leisure and pilgrimage routes. Akasa Air is growing its trade distribution. SpiceJet technically has series fare products but their current financial situation makes large commitments risky — verify their trade desk status before engaging.
What is the typical advance booking window for securing series allotment in India?
Agents securing peak-season allotment (summer, Diwali, Christmas) typically need to approach the airline's trade desk 3–6 months before the series start date. For shoulder-season or non-peak routes, 6–8 weeks in advance may be sufficient. High-demand routes like Delhi-Srinagar and metros-to-Leh for the summer season are competitive — agents with existing airline relationships get first access.
What happens if I can't fill my series-fare seats on a particular departure?
Most series-fare contracts allow you to release unsold seats back to the airline's general inventory by a specified deadline — often 21–30 days before departure — with reduced or no penalty. Inside that window, you may incur a release fee or be required to pay for unsold seats. The specific terms are in your allotment contract. Read the release clause carefully before signing — it determines your effective risk exposure if a week's packages don't sell.
Can I sub-agent series fare seats to other travel agencies?
This depends on the terms of your series-fare contract with the airline. Some contracts permit onward distribution to sub-agents; others require the allotment holder to be the final seller to the end passenger. Many agents in the Indian trade do distribute series inventory through agent networks, but verify this is explicitly permitted in your contract — distributing inventory without permission can lead to contract termination.
Where can I find information about available series fare allotments in India?
There's no public marketplace for series fares — they're negotiated bilaterally between airlines and agents. Platforms like agentbazar.in and travel agent associations (TAAI, IATO, ADTOI) are good places to learn about available allotments through the trade community. Established B2B travel platforms like FlightGPT Partner (agent.flightgpt.in) also facilitate group fare queries for registered travel agents.
