Using the best motorized wheelchair can enable you to travel more easily and navigate through major airports, which sometimes requires you to travel long distances in a short amount of time to get from the entrance to your gate.

But some passengers are even going so far as to fake a disability so they can use a wheelchair to get through the airport more quickly and easily, Market Watch reported.

In order to get wheelchair assistance from an airline, passengers don’t have to show any proof that they have a disability or have been injured. They are only required to “self-identify” as a person with who needs extra assistance because of an injury or disability, according to the U.S. Department of Transportation.

Airlines are then required to provide assistance, including helping passengers getto their gate and into their seat on the plane.  The escort service is provided free of charge.

People in wheelchairs or with disabilities who may need more time and extra assistance to board are usually allowed on the plane first. In many cases, they can skip the security line at U.S. airports.

Experts say that since many disabilities and injuries are not necessarily visible, it’s difficult to distinguish between genuine wheelchair users and fakers.

MarketWatch notes that if you want VIP service without faking an injury, you can pay extra for a golf-cart to take you through many airports. However, you will have to pay a bit. The article notes that for example, American Airlines offers “five star service” at some airports, which includes airport lounge access, assistance connecting to other airlines and an escort to baggage claim. It requires a reservation at least 24 hours in advance and costs $350.

If you want to cut down on your time in line, do it the legitimate way by joining TSA PreCheck and Global Entry also help cut down on time in line, particularly for regular business travelers. PreCheck costs $85 and lasts five years. Global Entry, which is recommended for international flyers, costs $100 and also lasts five years.
