Sentient Jet Card: How It Works, What It Costs and Who It Fits

How the Sentient Jet card works

Sentient’s jet card page lists two cards with prices, each sold as a 25-hour block: the SJ25 for light jets, and the SJ25+, bought separately for the Mid, Super-Mid or Large Cabin category (Provider-stated, 2026-09-25). Both card pages state “Jet Card hours that never expire”.

The SJ25 allows an “Upgrade to another jet size at fixed hourly rates”, and the SJ25+ an “Upgrade or downgrade”, a feature known as interchange.

Sentient’s SJ25+ card page describes Sentient Jet, LLC as “an ‘Air Charter Broker’ under DOT regulations” and states: “Sentient acts as authorized agent for the Cardholder … to contract for transportation services with FAR Part 135 Direct Air Carriers that operate and exercise full operational control over those flights at all times” (retrieved 2026-09-25). An air charter broker sells or arranges charters flown by a direct air carrier. We did not find the carriers named in Sentient’s public materials (checked 2026-09-25); the DOT’s broker rule requires a broker to give you the carrier’s corporate name before you contract for a specific flight (14 CFR 295.24(a)(1), eCFR issue date 2026-09-15).

What a Sentient Jet card costs

The card pages show no date; we read these figures on 2026-09-25, and the pages’ site metadata records a last update on 2026-04-16.

The base rate is the headline, not the invoice. Each card page states “Fuel Surcharge and Federal Excise Tax will apply”, and the surcharge amount is not published (checked 2026-09-25). Federal excise tax (FET) is 7.5% of the amount paid for taxable air transportation (26 U.S.C. §4261(a)).

Also not published (checked 2026-09-25): daily minimums, taxi-time billing, de-icing, repositioning, peak-day charges, initiation or annual fees, and an international fee schedule.

Estimate, one domestic SJ25 hour: the $7,324 base hourly rate (Provider-stated, 2026-09-25) plus 7.5% FET under 26 U.S.C. §4261(a) ($549.30) is at least $7,873.30. It excludes the fuel surcharge, any tax on that surcharge, the federal segment tax and any unpublished charge. With those missing, no full effective rate can be computed; the cost calculator follows the same “at least” rule.

Both card pages state a 12-month lock on hourly rates but do not say whether it covers the fuel surcharge. They also advertise round-trip “efficiency discounts” of 15% (SJ25) and “Up to 15%” (SJ25+) on “qualifying” trips, without saying what qualifies. What rate locks and fuel clauses cover.

Sentient’s site also has a landing page for a Large Cabin Edition Jet Card, with an enquiry form and no rates or terms (Provider-stated, checked 2026-09-25).

Availability, notice and booking

Sentient’s availability promise depends on notice, or callout. A Sentient blog post dated 2026-09-28 says card owners get “guaranteed availability with 48 hours’ notice on standard travel days, and 120 hours’ notice on a limited number of peak travel days” (Provider-stated); it covers both the SJ25 and the SJ25+. Each SJ25+ card page also says it “offers guaranteed access” to its cabin category.

For Europe, Sentient states that once you have landed in London, access is “guaranteed with 72 hours’ notice (within zones)”; the zones are not defined publicly (checked 2026-09-25).

Peak days exist but are not listed. A footnote on the Mid jet page reads: “Sentient cannot guarantee eight passengers on a Mid jet during designated Peak Travel Days.” Apart from the 120-hour notice, no count, dates or surcharge for those days is published, and neither are cancellation terms or aircraft-substitution rules (checked 2026-10-04).

Bookings run through Sentient’s app, text messages or the Card Owner web portal, backed by what Sentient calls “an extensive 24/7 customer service operation”.

Coverage and aircraft

Sentient’s international page, the source of the 72-hour notice above, lists “Extended, guaranteed access to popular EU destinations like Paris, Zurich, Milan and Frankfurt” and “Transatlantic routes with dynamic, competitive pricing”.

Sentient lists example types and a passenger maximum for each category (Provider-stated, 2026-09-25):

• Light (SJ25): Phenom 300, CJ series; up to 7 passengers.
• Mid (SJ25+): Citation Excel/XLS, Hawker 800XP series; up to 8, which Sentient “cannot guarantee” on designated Peak Travel Days.
• Super-Mid (SJ25+): Challenger 300 series, Citation X; up to 8.
• Large Cabin (SJ25+): Challenger 600 series, Gulfstream IV/400 series, Global series; up to 12.

Sentient words the SJ25+ guarantee as access to a cabin category, not to a specific aircraft type. SJ25+ cards include “Premier aircraft with guaranteed, complimentary Wi-Fi”; Wi-Fi terms for the SJ25 are not published (checked 2026-09-25). See how interchange across categories works.

Financial safeguards

Sentient describes itself as “now a Flexjet company” (Sentient release, 2025-12-16). That identifies the owner; it says nothing about how card payments are held.

We found no statement on escrow or segregated accounts for card funds, on refunds of unused hours, or on any guarantee of prepaid funds in Sentient’s public materials (Not published, checked 2026-09-25). Under escrow or segregation, a buyer’s money is held apart from the seller’s operating funds. See how to assess safeguards before you prepay.
