Modern jet airliners typically cruise at speeds between 550 and 600 mph (Mach 0.85 to 0.90), while private jets may operate at similar or slightly higher speeds but can save time by avoiding hub airports and delays. Factors such as aircraft design, altitude, wind conditions, and regulatory limits influence actual flight speeds. Despite advancements in technology, commercial airliner speeds have remained relatively stable due to economic and environmental considerations. Understanding these dynamics helps travelers make informed choices between commercial and private aviation options.

In 2026, the cost of jet aircraft varies significantly, with new private jets priced from $2 million for very light jets to over $400 million for customized VIP airliners, while charter rates range from $1,500 to $28,000 per hour based on aircraft type. For most business travelers, chartering is more economical than ownership, especially for those flying fewer than 200-300 hours annually, as ownership entails substantial fixed and variable costs. Jettly, a digital private jet charter platform, offers a transparent marketplace for on-demand bookings, allowing users to compare costs and access over 20,000 aircraft globally. Key strategies for reducing costs include choosing the right aircraft size, being flexible with travel times, and utilizing empty leg flights.

Empty planes, or flights operating with few or no passengers, are common in aviation due to regulatory requirements, aircraft repositioning, and maintenance needs. Airlines often operate these flights to retain valuable airport slots, while private jet operators create "empty legs" that can be booked at discounted rates. Although ghost flights contribute to significant CO₂ emissions, platforms like Jettly help travelers take advantage of empty legs, improving efficiency and reducing waste. Understanding the dynamics of empty flights can enhance travel experiences and offer unique opportunities for passengers.
