Continuing strong demand for jet charter options has compelled private aircraft charter broker Paramount Business Jets (PBJ) to expand its Paramount Jet Card program with a $1 million deposit tier, the company said Tuesday.

Paramount’s Private Jet Membership Card offers a pre-paid program that delivers access to private jets with as little as four hours of notice. Customers can charter any size aircraft on a per-trip basis rather than committing to long-term agreements. PBJ promotes the program as a flexible alternative to traditional 25-hour jet cards and private jet memberships.

“The Paramount Jet Card provides access to more than 4,000 of the safest and most luxurious private jets in the world,” said PBJ founder and CEO Richard Zaher. "The new $1 million deposit tier allows clients to enjoy all the advantages of on-demand aircraft charter on their schedule, without any delay for bank transfers or account verification."

Clients can access a Paramount Jet Card with a deposit as low as $100,000 held in a dedicated account available for use only by the cardholder. That amount locks in a guaranteed management fee of 16 percent of the total charges for each trip, or $1,600, whichever is greater.

Larger deposits provide access to even lower management charges and travel credits that travelers can apply to in-flight catering, automobile rentals, and other concierge services. A $1 million deposit locks in a 10 percent trip management fee—the lowest percentage available—and caps the maximum commission per trip at $30,000 for trips priced more than $300,000.

Paramount promises to refund unused jet card reserves whenever the client wishes; the program imposes no expiration dates or monthly service fees.
