Who is responsible for your flight: the operator, the broker, the aggregator

In private aviation three different roles stand between the customer and the aircraft. The contract is signed with one of them, and on the day of departure the questions arrive for all three at once. Here is who answers for what.

The operator is the company holding an air operator certificate, with aircraft and crews. The operator performs the flight and answers for safety, for the airworthiness of the aircraft and for the crew's qualification. It is the only participant in the arrangement carrying legal responsibility for the flight itself.

The broker finds the flight that fits the task and runs the deal. A broker owns no aircraft and holds no operator certificate. The broker answers for the choice of operator, for checking that operator's documents and insurance, for the terms of the contract, and for making the delivered flight match the one that was described.

The aggregator is a platform with an order form. It displays offers and passes the request onward. An aggregator's responsibility ends when the request has been passed on.

I look at this arrangement from the operator's side: my company is a working operator, and as of 2024 it had ten machines under management, five aeroplanes and five helicopters. Responsibility for a flight rests on the operator certificate, and it cannot be handed over to a broker or a platform. An aircraft above a certain take-off weight requires an operator airline in any case, under a management and technical operations agreement.

The practical difference shows up in three situations.

1. An aircraft substitution a day before departure. The operator explains the reason. The broker spends that day finding a replacement and recalculating the terms. The aggregator reports that the offer has been withdrawn.

2. A weather delay at the destination. The commander makes the decision and the operator arranges the alternative. The broker tells you about it before you have set off for the terminal.

3. A claim after the flight. The party to the contract answers it. Where the contract was signed with an aggregator, it emerges that its subject matter is information services.

What to check before signing:

▪️ Which party the contract is actually with, and which of the three roles that party occupies. ▪️ Whether the operator holds a current air operator certificate for the type of carriage required. ▪️ Passenger liability insurance: the limit and the period the policy runs for. ▪️ Who specifically handles the flight on the day, and how to reach that person outside the general mailbox.

The arrangement with a broker works because the broker has a standing interest: a client who flies once a month is worth more than a single transaction. The operator optimises the utilisation of its own fleet, which is a reasonable position for that business. Those two aims will not always coincide.
