What a concierge agency should look for.

A concierge agency doesn't need another provider promising "access." It needs a partner capable of protecting the client experience without hiding who's actually operating the flight. The evaluation has to cover both the aviation itself and how the partner handles information, changes, and exceptions.

Five dimensions

### Authority and sourcing The partner has to identify the direct air carrier, the applicable authority, and the specific aircraft. In the United States, diligence should include the Part 135 certificate, the D085, DOT economic authority, and insurance where relevant. NBAA lists these as part of carrier screening.

### Mission fit The agency should be asked about passengers, routing, baggage, pets, schedule, airports, runway restrictions, permits, and flexibility. A provider that quotes before understanding the mission is optimizing for sales speed, not execution quality.

### Operational control There should be a day-of-flight contact and a protocol for AOG, aircraft substitution, weather, slots, permits, or delay. The agency shouldn't be the only channel between passenger and operator when an urgent operational decision needs the carrier's authority.

### Economic transparency The partner should explain whether the agency earns a commission, whether the brokerage adds a margin, and what fees go to third parties. DOT's Part 295 covers disclosures on capacity, relevant relationships, total cost, and direct charges.

### Commercial protection The agreement should define ownership of the relationship, non-circumvention if one is negotiated, confidentiality, brand use, personal data, cancellation, and dispute resolution. A commercial-protection clause shouldn't block the client from getting the information they need about the operator.

The practical test

Before signing, ask for a full sample quote, a flight confirmation, a COI, and an example of how a substitution gets communicated. There's no need to demand confidential information about another client — it's enough to see whether the process actually distinguishes an estimate from a confirmation, and marketing from evidence.

A good white-label relationship makes the agency look organized. It doesn't make the operator disappear. The agency keeps the relationship. The partner brings aviation judgment. The carrier keeps the operation and the authority that comes with it.
