OAG is a global travel data provider with headquarters in the UK. The company was founded in 1929 and operates in the United States, Singapore, Japan, Lithuania and China. It has a large network of flight information data including schedules, flight status, connection times, and industry references such as airport codes. The "Official Aviation Guide of the Airways" was first published in February 1929 in the United States, listing 35 airlines offering a total of 300 flights. After the Guide was taken over by a rival publication in 1948, the September issue carried the OAG title for the first time. OAG was founded in Chicago, but moved to the suburb of Oak Brook, Illinois, in 1968. The "ABC World Airways Guide" containing maps and tips for travellers was first published in the UK in 1946. The integration of the ABC and OAG brands occurred following the acquisition of OAG Inc. in 1993 by Reed Elsevier which already owned ABC International. OAG had acquired SRDS, an ad rate information company from Macmillan Inc., a sister Maxwell company, in 1992; Reed Elsevier sold SRDS to a buyout firm in 1994. In August 1996, all products from the combined ABC and OAG businesses were rebranded as OAG. More information...
