Frontier Airlines manages to successfully offer both low fares as well as outstanding service, and is one of only a handful of airlines in the world that features live DirecTV service in every seat on every flight. In 2006 Frontier was named one of the "Top 10 Domestic Airlines" in Travel & Leisure World's Best Awards for the fourth consecutive year. From its hub in Denver Frontier flies to almost 50 gateways in the US plus 2 in Canada and 8 more in Mexico. Since April 2005 the airline has operated a fleet exclusively comprised of Airbus aircraft, and with an average age of less than 2 years it boasts one of the youngest fleets of any US carrier. Those planes can easily be distinguished thanks to the popular wildlife photos, or "spokesanimals" that are emblazoned on the aircrafts' tails in lieu of the traditional airline logo.
