Czech Airlines, often referred to as CSA, is the national airline of the Czech Republic. CSA flies from New York (JFK) as well as Toronto and Montreal to its hub in Prague's Ruzyn International Airport, with service to over 60 cities in more than 40 countries in Europe and the Middle East. Prague's central location in the heart of Europe make it an especially ideal gateway to up-and-coming Eastern European destinations in the CSA network such as Tallinn, Riga, Vilnius, Krakow, Kiev, and Ljubljana. The airline's membership in the SkyTeam alliance allows it to offer codeshare service from other US cities in conjunction with Delta Airlines. CSA has won accolades from the Association of European Airlines for its outstanding on-time performance record, frequently the best in Europe. They were also named Best Airline in Eastern Europe by Global Traveler magazine in 2005 and Best Airline Based in Central/Eastern Europe by the Official Airline Guide in 2004, 2005 and 2006.
