On-Market vs Off-Market Aircraft: What Buyers Should Know 

When buyers begin searching for an aircraft, they usually start with public listings. But the aircraft market also includes aircraft that are available without being advertised, often described as off-market. Understanding the difference, and the advantages and limitations of each, helps buyers search more completely and evaluate opportunities more carefully.

What on-market means

An on-market aircraft is openly offered for sale: listed on aircraft sales platforms, promoted by brokers and visible to the wider market. Specifications, photographs and an asking price, or an indication that pricing is available on request, are typically published.

Advantages for buyers

• Visibility: listed aircraft can be compared directly against each other.
• Information: specifications and basic details are usually readily available.
• Price reference: asking prices and time on market give a sense of seller expectations.
• Process: sellers who have publicly listed are generally prepared to transact.

Limitations

• Competition: well-presented, well-priced aircraft can attract several buyers at once.
• Incomplete picture: listings show only part of the available supply.
• Listing quality varies, and published information should always be verified.

What off-market means

An off-market aircraft is one whose owner is willing to sell but has chosen not to advertise publicly. Owners may prefer this for several reasons: privacy, a wish to avoid the aircraft being widely circulated, a sale tied to the timing of a replacement aircraft, or simply an openness to the right offer without an active sales campaign.

Off-market opportunities are typically identified through direct relationships with owners, operators, managers and other industry contacts, rather than through listings.

Advantages for buyers

• Access to aircraft that other buyers may not be aware of.
• Potentially less direct competition during negotiation.
• Discretion for both parties, which some buyers also value.
• Opportunities to find a specific configuration or specification that is not currently listed.

Limitations and risks

• Less information is available upfront, and price discovery is harder.
• Sellers who are not actively marketing may be less motivated or slower to commit.
• Off-market does not automatically mean better value; pricing may reflect the seller's expectations rather than market evidence.
• Chains of intermediaries can obscure who actually represents the aircraft, and whether they are authorised to do so.

Verify mandate and ownership. With any opportunity, but especially off-market ones, buyers should confirm who owns the aircraft and who is authorised to represent the sale before sharing sensitive information or committing funds.

Pricing: listed versus unlisted

On-market asking prices provide a reference point, but they are not transaction prices. Off-market aircraft have no published price at all, which makes independent valuation even more important. In both cases, the buyer should assess value from the aircraft's own characteristics: time and cycles, program status, upcoming inspections, records, damage history, equipment and condition, set against comparable aircraft and current supply.

Due diligence is the same in both cases

An off-market sale should never mean a lighter process. The same disciplines apply regardless of how the aircraft was found:

1. Confirm ownership, authority to sell and the absence of undisclosed liens through the appropriate legal checks.
2. Review the maintenance records and component histories in detail.
3. Agree a clear LOI with defined inspection scope and deposit terms.
4. Use an independent escrow agent for deposits and closing funds.
5. Complete a pre-purchase inspection at a qualified facility.
6. Finalise terms through a purchase agreement prepared by aviation counsel.

Questions to ask about any opportunity

• Who owns the aircraft, and who has the mandate to sell it?
• Why is the aircraft being sold, and on what timeline?
• What is the status of engine and APU programs, and are they transferable?
• When are the next major inspections due?
• Are the records complete and available for review?
• Is there any damage history, and how was it documented?
• How long has the aircraft been available, and has the price changed?

Clear, consistent answers to these questions are a good sign. Vague or shifting answers are a reason for caution, regardless of how attractive the opportunity appears.

A complete search uses both

For most buyers, the strongest approach is to consider both on-market and off-market aircraft against the same criteria. Public listings establish a picture of available supply and pricing expectations; off-market sourcing extends the search to aircraft that would otherwise be missed. Evaluating them side by side helps buyers recognise genuine value and avoid paying a premium simply because an aircraft was presented as exclusive.

A note for sellers

Sellers face the mirror image of this choice. A discreet sale protects privacy but reaches fewer buyers; an open listing maximises exposure but makes the sale visible. Some sellers begin discreetly and move to wider marketing later. The right approach depends on the aircraft, the market and the owner's priorities.

Timing also plays a role. An aircraft that is off-market today may be listed next month, and a listed aircraft may be withdrawn if the owner changes plans. Monitoring the market continuously, rather than taking a single snapshot, gives buyers a more accurate view of what is genuinely available.

How ATSJETS supports buyers

ATSJETS can coordinate aircraft searches that cover both listed aircraft and opportunities identified through its network, screen candidates against the buyer's mission and criteria, and support valuation, LOI coordination, records review and pre-purchase inspection coordination through to closing. Buyer requirements and identity are handled with discretion throughout.
