The Lear 25 jet charter is a twin engine business jet produced by Learjet, a Bombardier company. It is known as one of the fastest light jets and boasts speeds exceeding 500 mph. The Lear 25 is typically configured to seat eight business executives comfortably and with the added amenity of an enclosed lavatory. One of the most popular light jets, the Lear 25 has an impressive range of more than 950 nautical miles. To further increase the range of the Lear 25, Learjet introduced the Lear 36, which added nearly 500 miles by reducing the cabin length. The Lear 25 or 36 would be ideal for an executive charter flight to Chicago, Illinois to Phoenix, Arizona.
