Semi-Private Jets 2026: JSX vs Aero vs Tradewind (and What Happened to Set Jet)
You searched "Set Jet vs JSX" because a friend mentioned semi-private as a middle ground between first-class and full charter. You clicked the top three results and they were two years out of date. You read the JSX summer fare headline of $179 one-way and could not figure out which routes actually cost that. You called your travel advisor about Set Jet membership and learned it shut down in early 2024. You still want a semi-private option for a holiday LAX-Cabo run, and you cannot tell whether Aero, JSX, or Tradewind is the right pick.
This guide gives you the actual 2026 semi-private operator landscape: which carriers are flying, what they cost, which routes they serve, and where each one wins versus first-class or full charter. Real fares. Real aircraft. Real routes. Travel Anywhere is the AI-powered travel planning platform at travelanywhere.chat that helps travelers compare semi-private operators by route, season, and aircraft preference and books the right product for each trip type.
TL;DR: JSX operates 51 Embraer regional jets + 2 ATR 42-600 turboprops with by-the-seat fares from $179-$219 one-way (summer 2025 promo to typical pricing) across 60+ US routes, with private terminals and 30-minute arrival cutoffs. Aero flies custom 16-passenger black jets with one-ways from $950 LAX-LAS to $1,900-$2,250 LAX-Cabo, $1,900-$1,950 LAX/SFO-Aspen, and 2026 Miami expansion (Miami-LAX Nov 19, Miami-Aspen Dec 17). Tradewind Aviation operates Pilatus PC-12 and Citation CJ3 with fares from $200 between Caribbean islands to $750 Westchester-Stowe/Nantucket, focused on Northeast US and Caribbean inter-island. Set Jet ceased operations in early 2024 after operating Bombardier Challenger and Global jets on US membership routes. Best fit: JSX for budget semi-private domestic US, Aero for premium West Coast and ski-country, Tradewind for Caribbean and Northeast short-hauls.
Key Takeaways
- JSX by-the-seat fares run $179-$219 one-way on most domestic routes, with Hop On fares of $219 the typical published rate and $179 summer promo fares appearing on select routes. JSX operates 51 Embraer regional jets + 2 ATR 42-600 turboprops with 30-seat cabins configured at business-class legroom (no middle seats), complimentary drinks and snacks, and private terminal access with 30-minute arrival cutoffs.

- Aero one-way fares run $950 LAX-LAS, $1,900-$2,250 LAX-Cabo, $1,900-$1,950 LAX/SFO-Aspen. Aero operates custom 16-passenger black jets out of private terminals with 30-minute arrival cutoffs, one checked bag plus one carry-on, drinks and snacks onboard. 2026 expansion adds Miami-LAX (Nov 19, 2026) and Miami-Aspen (Dec 17, 2026) routes.

- Tradewind Aviation operates Pilatus PC-12 (short range) and Citation CJ3 (medium range) with fares from $200 between Caribbean islands to $750 Westchester-Stowe/Nantucket typical opening rates. Focus is Northeast US (Westchester base) and Caribbean inter-island connectivity (Anguilla, St. Barths, Nevis, Virgin Gorda). Source: SherpaReport, Tradewind Aviation official site.
- Set Jet ceased operations in early 2024. The membership model offered scheduled by-the-seat private flights on Bombardier Challenger and Global jets across US routes. Members were notified of the shutdown without warning. The shutdown signals the high cost of fleet-heavy semi-private and the difficulty of scaling membership against JSX's public-charter model.
- Semi-private is a middle product, not a private substitute. You share a 16-30 seat cabin, you fly published schedules (not on-demand), and you do not control departure time. The product wins over first-class on terminal experience and over full charter on price. It loses to charter on flexibility and routing.
- Pick semi-private when: your route is published, your dates are flexible, your group is 1-4 people, and you value private terminal access and 30-minute boarding. Pick full charter when: your route is off-network, you need on-demand timing, your group exceeds 6 passengers, or you need same-day departure.

What Is a Semi-Private Jet Actually?
A semi-private jet is a scheduled by-the-seat air service that operates under FAA Part 135 charter rules rather than Part 121 scheduled commercial rules. The technical structure: you buy an individual seat on a flight, but the aircraft operates as a public charter rather than a scheduled airline. This gives operators private-terminal access, no TSA security lines for many routes, and 30-minute arrival cutoffs while still selling fares per seat.
The semi-private category sits between first-class commercial and on-demand private charter on three dimensions: cost (much lower than charter, often comparable to first-class), flexibility (less than charter, more than commercial), and product (private terminal but shared cabin).
The category was pioneered by JSX (founded 2016) and grew with Aero (2019), Tradewind Aviation (1992, but pivoted to semi-private around 2015), Set Jet (2018-2024), and a handful of smaller regional operators. The 2024 Set Jet shutdown indicates the category is winnowing toward operators with scale economics (JSX) or premium positioning (Aero, Tradewind).
How Much Does JSX Really Cost in 2026?
JSX is the largest semi-private operator in the US by fleet size and revenue. The fleet is 51 Embraer regional jets (mostly Embraer ERJ-135 30-seat configurations) + 2 ATR 42-600 turboprops as of April 2026.
JSX 2026 fare structure:
| Fare type | Typical price | Routes covered |
|---|---|---|
| Hop On (base) | $219 one-way | All published routes |
| Summer promo | $179 one-way | Select routes (May-Aug 2025 promo) |
| Premium routes | $349-$549 one-way | Aspen, Mammoth, ski-country routes |
| Add-ons | $0-$50 | Premium seat selection, extra bag |
JSX cabin configuration:
- 30 seats per Embraer ERJ-135 (versus 50-60 in commercial config)
- Business-class legroom
- No middle seats
- 2-1 seat arrangement
- Complimentary drinks (beer, wine, spirits, soft drinks) and snacks
- Private terminal access (often dedicated FBO-style terminals)
- 30-minute arrival cutoff (versus 60-90 minute commercial)
JSX operates 60+ US routes including: Burbank, Oakland, Phoenix, Las Vegas, Reno, Mammoth, Aspen, Denver, Austin, Dallas, Houston, Nashville, Atlanta, Miami, Orlando, Westchester, Boston, Burbank, Carlsbad, Concord, Napa, San Diego, and more.
"JSX has structurally beaten Set Jet, Surf Air, and other membership models by selling individual seats at first-class prices," notes a 2026 Private Jet Card Comparisons analysis on JSX's 10-year milestone. "The public charter regulatory category gives them private terminal access without the cost structure of a full Part 135 charter operator. That is the sustainable economics most semi-private operators failed to find." Source: Private Jet Card Comparisons, JSX 10 years milestone analysis April 2026.
How Does Aero Compare?
Aero is the premium semi-private operator focused on West Coast and ski-country routes. The fleet is custom 16-passenger black jets (originally Embraer Legacy 600 conversions, with later additions). The product positioning is closer to first-class international than to JSX's domestic semi-private.
Aero 2026 published pricing:
| Route | One-way starting price |
|---|---|
| LAX-Las Vegas | $950 |
| LAX-Los Cabos | $1,900-$2,250 |
| LAX-Aspen | $1,900-$1,950 |
| SFO-Aspen | $1,900-$1,950 |
| Miami-LAX (Nov 19, 2026 launch) | TBA |
| Miami-Aspen (Dec 17, 2026 launch) | TBA |
Aero product details:
- 16-passenger custom cabin (versus JSX's 30-seat)
- Private terminal access at LAX, SFO, JFK, MIA, ASE
- 30-minute arrival cutoff
- One checked bag + one carry-on included
- Drinks and snacks onboard
- Same-day rebooking flexibility on most fares
Aero's structural bet is premium pricing on premium routes (Aspen ski season, Cabo holiday, Miami winter). The 2026 Miami expansion signals the operator is building national reach rather than staying West Coast-only.

What Are Tradewind Aviation's Routes and Pricing?
Tradewind Aviation operates a different model from JSX or Aero: small-aircraft semi-private with Pilatus PC-12 (short-range) and Citation CJ3 (medium-range), focused on Caribbean inter-island and Northeast US short-haul routes from a Westchester (HPN) base.
Tradewind Aviation 2026 pricing:
| Route type | Typical starting price |
|---|---|
| Caribbean inter-island (St. Barths to Anguilla, etc.) | $200 one-way per seat |
| Westchester to Stowe (VT) | $750 one-way |
| Westchester to Nantucket | $750 one-way |
| Westchester to Martha's Vineyard | $750 one-way |
| Westchester to Cape Cod | $750 one-way |
| Citation CJ3 longer hauls | $1,500-$2,500 one-way |
Tradewind aircraft:
- Pilatus PC-12 (8-9 seats, short range)
- Citation CJ3 (6-7 seats, medium range)
- Both operate out of private terminals
- Shared-charter model on most routes (4-6 passengers per flight typical)
The Caribbean inter-island product is the standout: $200 fares between St. Barths, Anguilla, Nevis, and Virgin Gorda compete favorably with the alternatives (Tradewind beats both commuter ferries and on-demand private inter-island charter). Northeast US Stowe/Nantucket routes during ski and summer season are the second-strongest product.
What Happened to Set Jet?
Set Jet ceased operations in early 2024 after roughly six years of operation. The membership model charged a monthly or annual fee for access to scheduled by-the-seat semi-private flights on Bombardier Challenger and Global jets across US routes (LAX-Aspen, LAX-Cabo, NYC-LA, etc.). Members were notified of the shutdown without significant advance warning.
The structural lessons from Set Jet:
- Fleet economics matter. Set Jet flew Bombardier Challenger and Global jets (full charter-class aircraft) sold by the seat. The per-flight operating cost was high. The yield per seat needed to be high to break even. Demand at those price points was inconsistent.
- Membership versus pay-as-you-fly. Set Jet required membership; JSX sells individual fares. When demand wobbled, JSX could keep filling seats at lower published fares; Set Jet's membership model limited yield management flexibility.
- Route concentration risk. Set Jet concentrated on premium West Coast and Cabo routes. JSX diversified across 60+ US domestic routes. The diversification helped JSX absorb route-level demand shocks.
Set Jet's shutdown is a leading indicator that semi-private is consolidating around either scale (JSX) or premium niche (Aero, Tradewind), not the membership-middle that Set Jet tried to occupy.
When Does Semi-Private Beat First-Class Commercial?
The cost comparison varies by route, but the structural advantage of semi-private over first-class commercial is consistent across operators:
Semi-private wins on:
- Private terminal access (no TSA security lines for many routes)
- 30-minute arrival cutoff (versus 60-90 minute commercial)
- No middle seats, business-class legroom
- Faster baggage retrieval (often delivered planeside)
- Smaller cabin reduces crowd noise and boarding chaos
First-class commercial wins on:
- Flight frequency on major routes (5-10 flights per day versus 1-2 semi-private)
- Lounge access at most major airports
- Lie-flat seating on longer routes (most semi-private is business-class seats, not lie-flat)
- Loyalty program credits (semi-private operators have limited loyalty integration)
Price comparison on LAX-NYC (one-way, similar season):
| Product | Typical price | Travel time | Terminal experience |
|---|---|---|---|
| United polaris business | $1,500-$3,500 | 5h 30m | Commercial terminal + lounge |
| Delta one | $1,500-$3,000 | 5h 30m | Commercial terminal + lounge |
| American flagship business | $1,500-$3,000 | 5h 30m | Commercial terminal + lounge |
| JSX (where available) | $219-$549 | Often slower (route-dependent) | Private terminal, 30-min cutoff |
| Aero | $1,200-$2,500 | 5h 30m | Private terminal, 30-min cutoff |
For LAX-NYC specifically, neither JSX nor Aero offers a direct service in 2026 (the route requires connection on those operators). For LAX-Aspen or LAX-Las Vegas, semi-private (especially Aero) beats first-class on both price and experience.
When Does Semi-Private Beat Full Private Charter?
Semi-private wins on price by a wide margin for 1-4 person travel on published routes:
LAX-Aspen one-way pricing (4 passengers):
- Aero semi-private (4 seats): $7,600-$7,800 total
- Full charter (4 passengers): $14,000-$22,000 typical light jet
- NetJets jet card hour cost: ~$14,000-$18,000 for the flight time on Phenom 300
Aero LAX-Cabo one-way pricing (4 passengers):
- Aero semi-private (4 seats): $7,600-$9,000 total
- Full charter (4 passengers): $18,000-$32,000 typical mid-size jet (Cabo requires range)
The semi-private advantage erodes above 6 passengers, on off-network routes, or when same-day departure is needed.

FAQ: Semi-Private Jets 2026
Is JSX the cheapest semi-private option?
For most domestic US routes, yes. JSX's $179-$219 fare range beats Aero ($950-$2,250), Tradewind ($200-$750), and on-demand charter ($1,500+ per hour). Aero is more expensive but operates on premium routes (Aspen, Cabo) where JSX has less coverage.
Did Set Jet really shut down?
Yes, Set Jet ceased operations in early 2024. Members were notified of the shutdown and Set Jet's Bombardier Challenger and Global fleet was returned to lessors or sold. Set Jet's membership fees were not refunded to all members; some pursued legal claims.
Can I fly semi-private internationally?
Limited international service. Aero operates LAX-Cabo (Mexico) and is expanding Miami-LAX. JSX operates Cabo and Mexican beach destinations seasonally. Tradewind operates Caribbean inter-island. For longer international (LAX-Europe, NYC-Caribbean), full charter or first-class commercial remains the only option.
Is semi-private actually private?
No. You share a cabin with up to 30 other passengers (JSX) or up to 16 (Aero, Tradewind PC-12 is 8-9). You do not control departure time. You do not control aircraft. You do get private terminal access, no TSA in many cases, and 30-minute arrival cutoffs.
Do semi-private operators have loyalty programs?
JSX has a Hop On Rewards program (modest rewards, not comparable to airline elite tiers). Aero, Tradewind, and most others have limited or no loyalty integration. The lack of loyalty rewards is a real cost for frequent travelers who would otherwise earn elite status on commercial airlines.
Are semi-private flights subject to TSA security?
It depends. JSX operates under public charter rules (Part 380), which means TSA security is not required for many JSX flights. Aero similarly operates under public charter rules with private terminals. Tradewind PC-12 flights are typically not subject to TSA. This is a key differentiator from commercial flights.
Can I bring my pet on a semi-private flight?
Yes, most semi-private operators allow pets in the cabin (no cargo hold pet shipping on these aircraft). JSX is particularly pet-friendly (in-cabin pets with $50 fee). Aero accepts well-behaved pets in cabin. Tradewind accepts pets with advance notice.
