Charter GDS for seat blocks
Blocks Master is a B2B distribution system for charter flights. You load a block of seats once — route, times, cabins, net and selling price — and your whole trade network sells it from the same live inventory: sub-agencies on your portal, agencies on their own branded shops and trade portals, and partner systems through an API.
The gap
Scheduled airlines sell through global distribution systems built around fares the carrier files. Charter seats rarely work that way. A tour operator or consolidator buys a block of seats on a chartered aircraft, at a net price, and then has to sell every one of those seats to travel agencies before departure — usually with spreadsheets, emails and WhatsApp groups standing in for an inventory.
That is where seats get sold twice, prices leak between agencies, and money is chased after the passenger has flown. A charter distribution system replaces the spreadsheet with one live inventory that every seller draws on, rules that decide who pays what, and a ledger that moves the money before the seat leaves your stock.
Blocks Master is that system. It is not a scheduled-airline GDS with charters bolted on: it is built around the block — the slice of an aircraft you hold — and around the network of agencies that sells it.
How it works
Enter the flight once: route, local times at both ends, cabins and how many seats you hold in each. Set the net price you paid and the selling price per adult, child and infant, and baggage tiers if the carrier allows them.
Give each agency a pricing grade and add rules by partner, trip type and time before departure. Each agency sees only its own price — never your cost, never another agency’s.
Top up an agency’s wallet and it can book at once. Every booking locks the seat, draws the wallet down, issues the ticket and lands on both statements in the same second.
Distribution
Agencies you sign up search, hold and ticket your charter seats on your trade portal, each with its own users, wallet and statement.
An agency can sell your seats to travellers on a white-label shop under its own domain, logo and colours, taking card payments into its own merchant account.
A larger agency can run its own trade portal for its own sub-agents, on its own domain, still drawing on your inventory.
Partner systems search and book through a documented API with a sandbox, idempotent bookings and webhooks — no screen required.
Share a block with another operator by Office ID, with limits on routes, seats per flight, value, sales cut-off and end date.
A flight stops selling at departure, and a sales cut-off can close it earlier. A full block can keep a waiting list.

| Spreadsheets & messaging | Scheduled-airline GDS | Blocks Master | |
|---|---|---|---|
| Built around | Whoever updates the file | Fares filed by the airline | Your charter block and your agency network |
| Double-selling | Common under pressure | Not applicable to private blocks | Impossible: seats are taken in the same transaction as the payment |
| Agency pricing | Sent by message, easy to leak | Not set by the block holder | Grades and rules per agency, never below your cost |
| Getting paid | Invoices chased after travel | Settlement through the airline’s plan | Prepaid wallets: the money is in before the seat is out |
| Agency branding | None | None | Agency logo on tickets and emails; shops and portals on its own domain |
| System-to-system | None | Through the GDS | Partner API with sandbox and webhooks |
Questions
It is a distribution system for charter inventory — a charter GDS in the sense that one inventory is distributed to many sellers and systems. It does not replace a scheduled airline’s GDS listing; it handles the seat blocks that scheduled GDSs were never built to sell.
No. Seats are reserved inside the same database transaction that takes the payment, with an update that only succeeds if the seats are still free. Two bookings for the last seat cannot both succeed.
No. An agency only ever sees the price its grade and the matching rules produce. Your net cost and other agencies’ prices never reach its browser.
No. Operators can share blocks with each other by Office ID, with limits you set, and a partner can only narrow those limits further.
Yes, as a separately licensed product: contracted room allotment counted per night, on the same wallets, grades and statements.
