United Airlines begins operations with Bombardier CRJ550.

Chicago, Illinois - United Airlines is preparing to introduce a new aircraft type on its regional routes later this month.

United Airlines is going to begin operations this month with Bombardier's new regional jet CRJ550. In fact, the aircraft is the existing CRJ700 with a modified cabin layout.

The CRJ700, which was operated by the US carrier, can accommodate 70 passengers in a regular seating arrangement. The CRJ550 features a stunning luxury First Class.

The passenger cabin of the CRJ550, however, is configured to accommodate ten passengers in First Class and 50 passengers in the Premium Economy and Economy Classes.

The CRJ550 is considerably more spacious than the existing 50-seater regional jets, such as the CRJ200 and the Embraer ERJ-145. For the First Class passengers, there is a self-service refreshment center where they can enjoy a wide range of drinks and snacks.

The CRJ550 will begin flights from Oct. 27. Tickets can be booked from Oct. 12. The plane will initially be deployed on routes between Chicago O'Hare and Allentown (Pennsylvania), Bentonville (Arkansas), Cedar Rapids (Iowa), Madison (Wisconsin), Richmond (Virginia) and Tulsa (Oklahoma).
