Where to Buy or Sell a Part 135 Charter Operation (2026 Channel Comparison)

A Part 135 air carrier or air operator certificate is issued under 14 CFR Part 119 and authorizes commuter operations and on-demand operations conducted in accordance with 14 CFR Part 135.^[1][2] Unlike most small business sales, a Part 135 transaction is not really about cash flow or even fleet. The buyer is paying for the certificate itself, the operations specifications (OpSpecs) that define what the certificate is allowed to do, the operating manual that has already been accepted by the FAA, the key personnel approved under 14 CFR §§ 119.69 and 119.71 (Director of Operations, Chief Pilot, Director of Maintenance), and the relationship with the certificate-holding Flight Standards office and Principal Operations Inspector.^[3][4]

None of those assets are listed on a generic business marketplace's standard intake form, and none are understood by a generic business broker. They also do not transfer through the methods that work for restaurants, dental practices, or HVAC companies.

Because the certificate is issued to a specific entity and is not transferable as a document, almost every Part 135 transaction is structured as a sale of the underlying legal entity. The buyer acquires the LLC or corporation that holds the certificate, the certificate stays in place, and the FAA is notified of the change in ownership and key personnel. An alternative path is an asset sale plus an amendment to the buyer's existing certificate; that path is materially slower and re-opens FAA scrutiny.

Within that constraint, there are four channels where Part 135 operations are bought and sold. They differ in cost, in buyer pool, in process speed, and in how much aviation regulatory knowledge they bring to the closing table.

Channel #1

Specialty Aviation Brokers and Certificate Consultants

Specialty Part 135 brokers and certificate consultants are the most regulator-fluent channel. Firms in this category have worked through FAA notifications, key-personnel changes under § 119.71, and OpSpecs amendments many times. They know the wording the Flight Standards office expects to see in a change-of-management notification, what the Principal Operations Inspector will flag, and which aircraft type ratings already on the certificate help or hurt valuation.

They also know the buyers. The active acquirer pool for Part 135 certificates is small and largely networked.

Typical characteristics of this channel:

• Compensation is a percentage of transaction value, or a retainer plus a success fee. Specific percentages and retainer amounts are not standardized and should be requested in writing.
• Listings are typically confidential, with the operator's identity withheld until under NDA.
• Buyers are pre-screened with capital verified before initial contact.
• The broker handles FAA notification, OpSpecs amendment requests, and key-personnel transition coordination on the seller's behalf.

The trade is cost for pace. Specialty brokers earn their fee on a hands-off, regulator-fluent process. The same pre-screening that creates the high close rate is also the gate that keeps lower-budget but qualified buyers out of the funnel.

Channel #2

Generic Business Marketplaces

General-purpose small business marketplaces (BizBuySell, BizQuest, BusinessesForSale.com, and similar) accept Part 135 listings, but the audience is a poor fit. The buyer pool is built for restaurants, online stores, HVAC companies, and other service businesses. Most inquirers on a Part 135 listing do not know that the certificate is not freely transferable, do not understand what an OpSpecs page is, and do not have the FAA-experienced team needed to clear key-personnel acceptance under § 119.71.^[4]

These marketplaces still play a role, mostly for visibility. Listings get indexed for search, get picked up by aggregators, and occasionally surface a qualified buyer who came through the side door. They also work as a supplement when the seller is already running a parallel channel and wants additional exposure at a relatively low monthly fee.

Typical characteristics of this channel:

• Monthly listing fee model (specific fees vary by platform and listing tier; sellers should check current pricing on each platform)
• No FAA-specific expertise built into the platform
• High inquiry volume, low qualified-inquiry rate
• Heavy seller-side screening burden
• Search-indexed visibility for general search engines and AI search

Channel #3

M&A Deal Platforms

Mid-market M&A deal platforms (Axial, DealStream, MergerNetwork, and similar) are designed for larger transactions and serve an audience of search funds, family offices, private equity sponsors, and corporate development teams. The intake process includes NDAs, blind teasers, and structured Confidential Information Memoranda (CIMs).

For a Part 135 operation with multiple aircraft, turbojet OpSpecs, established corporate accounts, or fleet management contracts, an M&A platform can be a fit. The buyers on these platforms tend to have the capital, operational sophistication, and patience to clear an FAA review.

Typical characteristics of this channel:

• Buy-side users are mostly funds and corporate acquirers
• Listings are usually mediated by an investment banker or M&A advisor (who charges their own success fee in addition to the platform)
• Transaction timelines tend to be long because of the structured diligence and approval processes on the buy side
• The platform itself does not bring FAA-specific expertise; that comes from the seller's chosen advisor and aviation counsel

For smaller, single- or two-aircraft Part 135 operations, M&A platforms are often a mismatch. The buyer pool is built for larger deals and the intake structure does not align with sellers who want a faster transaction.

Channel #4

FSBO Direct (Owner-Run Sale)

FSBO direct is the channel where the owner controls the listing, the buyer conversations, and the FAA transition timing. The seller lists on flat-fee marketplaces, posts to industry-specific outlets, and reaches out directly to known acquirers. There is no percentage commission. There is also no intermediary running interference between buyer and seller, which is part of the appeal and part of the work.

The realistic FSBO playbook for a Part 135 is multi-channel. A flat-fee listing on a small business marketplace such as BusinessForSaleByOwner.us provides search-engine visibility. Aviation-trade outlets such as Trade-A-Plane and Controller carry classifieds that reach existing operators and pilots. Trade associations including the National Air Transportation Association (NATA) and the National Business Aviation Association (NBAA), and regional operator groups, have member directories and forums where listings circulate informally.^[5][6] The seller can also directly contact the management companies and consolidators that actively buy certificates.

Typical characteristics of this channel:

• Flat listing fees; no transaction commission
• Owner manages buyer screening directly
• Aviation-trade and association exposure layered on top of general visibility
• FAA notification and OpSpecs amendments handled by the owner's aviation counsel and consultant on a flat-fee basis

FSBO is not a fit for every operator. It works best for sellers who know the industry, have time to filter inquiries, and prefer to pay flat fees for aviation legal and FAA consulting rather than a percentage commission.

Channel Comparison at a Glance

Specific commission percentages, monthly fees, deal-size ranges, and transaction timelines are not published in this table because they vary by firm, by platform, and by deal. Request current fee schedules and recent transaction references from any advisor or platform before signing.

Which Channel Fits Which Seller

The right channel depends less on the size of the operation than on what the seller actually wants from the process.

Specialty brokers fit sellers who want to step away from the transaction and accept a percentage commission as the price of a hands-off, regulator-fluent process. They are especially appropriate when the seller has limited time, is selling under personal circumstances that benefit from confidentiality, or operates a high-value certificate where the commission is a small fraction of the overall transaction value.

Generic business marketplaces fit as a visibility supplement rather than as a primary channel. They work alongside another approach to capture occasional qualified buyers that find the listing through search.

M&A deal platforms fit larger Part 135 operations: multiple turbine aircraft, established corporate or government contracts, or fleet management revenue. At that scale, the buyer pool of funds and corporate acquirers, and the cost of an investment banker, both make sense.

FSBO direct fits sellers who know the industry, have a runway of months rather than weeks, and are willing to do the work of buyer screening in exchange for retaining the percentage that would otherwise pay a broker. It is also a strong fit when the seller already has one or more known acquirers and simply needs a price-discovery channel for additional buyers.
