WestJet Airlines Ltd. is a Canadian low-cost carrier that provides scheduled and charter air service to 87 destinations in Canada, the United States, Mexico, Central America and the Caribbean. Founded in 1996, it is currently the second-largest Canadian air carrier, behind Air Canada, operating an average of 425 flights and carrying over 45,000 passengers per day. In 2012, WestJet carried 17,453,352 passengers, making it the ninth-largest airline in North America by passengers carried. WestJet is a public company with more than 9,600 employees, is non-unionized and is not part of any airline alliance. It operates variants of a single aircraft type, all from the Boeing 737 Next Generation family. The airline's headquarters is located adjacent to the Calgary International Airport, and its largest hub, in terms of daily departures, is Toronto Pearson International Airport. WestJet had passenger revenues of $3.4 billion (CAD) in 2012, and reported annual 2012 earnings of C$1.78 per share, a year-over-year increase of 68% compared with 2011 EPS. WestJet and WestJet Encore currently fly to 87 destinations in 15 countries throughout North America, including 34 cities in Canada and 21 in the United States. WestJet's largest hub in terms of daily departures is Toronto Pearson International Airport, the airline's main connection point in Eastern Canada. WestJet provides the most Canadian flights to Las Vegas and Orlando, offering non-stop routes (some of them seasonal) from eleven Canadian cities to Orlando and twelve to Las Vegas. Since 2008, WestJet is the largest international carrier, by volume of passengers, flying into Las Vegas. WestJet also serves 19 destinations in the Caribbean and seven in Mexico, some on a seasonal basis. In March 2010, Sean Durfy resigned from his position as WestJet's CEO, citing personal reasons. He was replaced by Gregg Saretsky, a former executive at Canadian Airlines and Alaska Airlines and previously Vice-President of WestJet Vacations and Executive Vice-President of Operations. In July 2010 WestJet announced service to Santa Clara, Cuba, New Orleans and Grand Cayman bringing the total number of destinations to 71. Service to New Orleans lasted only one season, and did not return the next year. In late 2010 WestJet announced it was wet leasing a Boeing 757 aircraft to expand service between Calgary and Edmonton to Honolulu and Maui, on a seasonal basis. Also that year, the Canadian Transportation Agency (CTA), an independent administrative tribunal of the Government of Canada that regulates airlines, found WestJet's baggage policies to be unreasonable and/or contrary to the requirements of the Canada Transportation Act and/or the Air Transport Regulations on several different occasions. On January 26, 2011, after Air Canada terminated Canadian service, WestJet announced plans to enter service to John Wayne Airport in Orange County, California from Vancouver and Calgary starting May of the year. In November 2011 WestJet won an auction for time slots at New York's LaGuardia Airport ushering in a return to service to New York. Details of Westjet's scheduled service to LaGuardia were officially announced in January 2012. In late 2012, WestJet further expanded into the United States by adding Chicago via O'Hare International Airport.
