Established in 1997, Star Alliance is currently the largest alliance, boasting the most member airlines, daily flights, destinations (over 1,300), and contries flown to by its members (over 190).
As the largest airline alliance, including rockstar first class products such as Singapore Airlines and Lufthansa, Star Alliance is certainly not to be ignored despite recent devaluations for premium cabin redemptions. Excellent coverage in Asia/Oceana (Singapore, Air NZ, EVA, ANA, Asiana, Air China), North America (Air Canada, United), and Europe (Swiss, Lufthansa, SAS, Adria) make this alliance an excellent choice. Star Alliance members are well represented as Amex, Citi, and Chase redemption partners.
