Air traffic rights are described using the “freedoms of the air” — a shorthand for what an airline is allowed to do across borders. If you want to understand SAATM, this is the vocabulary to learn, because the fifth freedom of the air is the specific right that turns a liberalisation agreement into a usable network.

The terminology sounds legalistic, but each freedom answers a plain commercial question: may I fly this sector, and may I sell seats on it? Everything else in a route business case — aircraft type, frequency, pricing — follows from the answer.

The Basics: Third and Fourth Freedoms

The basics are the third and fourth freedoms: carrying passengers from your own country to another, and bringing them back. Most existing bilateral agreements already cover these out-and-back rights, so they are rarely the sticking point.

What they produce, however, is a particular shape of airline. If every service must begin and end at home, the network is a set of spokes radiating from one base, each sector flown twice and sold once. Utilisation is capped by geography, and thin markets stay unserved because the only way to reach them is a dedicated rotation that a small demand pool cannot fund. That is the structural reason so many African city pairs remain unconnected despite obvious demand: the traffic exists, but not in the shape that out-and-back rights can monetise.

The Fifth Freedom of the Air, Explained

The real prize in SAATM is the fifth freedom. This is the right of an airline to carry paying passengers between two other countries, as part of a service that starts or ends in its home state. Picture an airline flying from its home country to a second country, then continuing on to a third — and selling seats on that final leg.

Why the onward leg changes the economics

Fifth-freedom rights are what allow airlines to build efficient regional networks instead of isolated point-to-point routes. The mechanism is simple: an onward sector that can be sold on its own carries its own revenue rather than depending on connecting traffic from the first leg. A route that fails as a dedicated rotation can succeed as the second leg of a triangle, because it inherits an aircraft and crew already positioned and adds local demand on top of through demand.

This is also why fifth-freedom access tends to raise frequency rather than just add destinations. Once a sector can be sold in its own right, the planning question shifts from whether the market supports a whole aircraft rotation to whether it supports a share of one.

Why it meets resistance

Fifth-freedom rights are exactly what protectionist bilateral deals tend to block, because they expose national carriers to more competition. From a transport ministry’s point of view, granting third and fourth freedoms admits a foreign carrier to a market it shares; granting fifth freedoms admits it to a market the national carrier may have considered its own domestic-regional preserve. In our view that distinction, more than any technical objection, explains why liberalisation stalls at precisely the freedom that would do the most good.

What SAATM Member States Commit To

Under SAATM, member states commit to granting each other these traffic rights automatically, rather than negotiating them route by route. They also agree to remove capacity restrictions — no artificial caps on how many flights or seats — and to let airlines set fares competitively. The reference rulebook for all of this is the Yamoussoukro Decision.

These three commitments are best read as a set, because any one of them alone is defeated by the others. Traffic rights without capacity freedom give you permission to fly a route you cannot scale. Capacity freedom without fare freedom gives you seats you cannot price to fill. Fare freedom without traffic rights is theoretical. The reason SAATM is described as a single market rather than a bundle of concessions is that the three only function together.

The legal lineage behind that rulebook is set out in our article on the Yamoussoukro Decision, and the wider framework in the hub piece on what SAATM is and how it works.

The Eligibility Condition: Genuinely African Carriers

There is one important eligibility condition. To benefit, an airline generally has to be genuinely African: substantially owned and effectively controlled by African states or their nationals, and properly licensed and safety-certified by its home authority. This keeps the market open to African operators while maintaining safety and ownership standards.

Two halves of that test do different jobs, and it is worth separating them. Ownership and control is an economic gate: it ensures the benefit of liberalisation accrues to African carriers rather than to non-African airlines setting up a nominal continental base. Licensing and safety certification is a technical gate: it ensures a carrier exercising continental traffic rights is properly overseen by an authority that can be relied on. A single market cannot function without both, since open access to a market with uneven oversight simply exports risk.

The practical implication for an operator is that ownership structures should be reviewed against this test before a network strategy is built around SAATM rights — particularly where external investment or leasing arrangements might be read as affecting effective control. Oversight capacity is one of the recognised implementation constraints, discussed in the barriers still facing SAATM.

Why the Fifth Freedom Is the Decisive Lever

Why does this matter so much? Because fifth-freedom access is the difference between a continent of disconnected routes and a continent with real networks. It is the single most powerful lever SAATM pulls — and the one that meets the most political resistance.

That combination is what makes it the honest measure of progress. Counting signatures tells you about intent; watching whether fifth-freedom sectors are actually being flown tells you whether the market is opening. In our view an operator or analyst tracking SAATM should watch the route filings and the timetables rather than the communiqués. The African Civil Aviation Commission, as executing agency, publishes its own reporting on implementation at afcac.org.
