The flight time on a private jet from London to New York can vary depending on several factors, including the type of aircraft, weather conditions, air traffic, and specific routing. 

On average, the flight time for a private jet between these two cities is approximately 8 hours. The distance is 3460 miles.

When time is of the essence, the allure of private jet travel has transcended luxury, offering business travelers an efficient alternative to commercial flights. With the ability to save between 2 to 4 hours every time you fly, private jet travel's time-saving benefits have become the primary selling point of the charter industry. Here are the following 6 ways private travel saves you time:

1. Streamlined Check-In and Security: When you fly on a private jet, you don't have to wait in long lines to check in or go through security. This means you can start your trip faster and you can spent significantly less time at the airport.
2. Direct Flights and Small Airports: Private jets can fly to smaller airports that are closer to where you want to go. These airports are not as busy as the larger ones, so you can arrive and leave more quickly.
3. Pick Your Departure Time: On private jets, you can choose when you want to leave. This makes things more flexible and saves time.
4. Easy Boarding and Deboarding: Private jets are smaller, so it's faster to get on and off them. Plus you don't have to wait for other people. This helps you move from the waiting area to the airplane quickly.
5. No More Layovers: Private jet travel often involves direct flights, eliminating the need for time-consuming layovers. This not only reduces travel time but also limits the stress associated with navigating unfamiliar airports during layovers.
6. Get More Done on the Jet: Private jets have more space for each person. This means you can do things like work or relax more comfortably. Business travelers can enjoy a more productive environment by not being bothered by noise or crowds.

While security measures are still in place for private jet travel, the process is much faster and less intrusive compared to commercial flights. 

Expect to spend between 5-15 minutes going through security at the private terminals. While private jet terminals often provide expedited check-in and boarding, security remains a crucial aspect of travel. Here's an overview of the security measures you might encounter when flying private:

1. Personal Identification: Just like on regular flights, you'll need to show an ID, like your driver's license or passport. This makes sure you're the right person to be on the jet.
2. Passenger Screening: Sometimes, there might be a quick interview or check about you before you fly. It's to make sure everything is okay.
3. Secure Facilities: Private jet terminals are designed to maintain a secure environment. Access to these terminals is often restricted to authorized personnel and passengers, minimizing the risk of unauthorized individuals entering the premises.
4. Aircraft Security: Private jets undergo rigorous security checks before each flight. Crew members conduct pre-flight inspections to ensure the aircraft is free of any potential threats or hazards. This includes checking the interior, cargo areas, and other relevant components.
5. Customs and Immigration: If you're flying to another country, customs and immigration procedures will still apply. Private jet terminals usually have designated areas where immigration officers can process your entry or exit.
