Best for world travel. One of the appeals of jet cards is their pay-per-dollar or -hour system, so users know the bottom line before they board. But often, this rate is limited to a predetermined service area, which may only include the U.S. and possibly Canada, Mexico, and the Caribbean. If you want to fly outside the zone, you’ll be tagged a “ferry fee” to cover the cost of flying the jet back to its base after it drops you off or comes pick you up. Sometimes it even covers the costs of overnight stay for the pilots. VistaJet, by contrast, recently eliminated this ferry fee worldwide. The carrier charges $40,000 for its program, plus a $10,000 lifetime membership fee. It also offers a single-flight service for $12,000 to $17,000 per hour. Its fleet of super-midsize and long-range jets is more suitable for long-haul flights than smaller jets. more
