PRAGUE, Oct 7 (Reuters) - Europe's Airbus broke

a major commercial barrier on Tuesday when its A320 family of

planes overtook the Boeing 737 to become the

most-delivered jetliner in history.

Boeing's ( BA ) decades-old record fell as a jet was delivered

overnight to Saudi carrier Flynas, bringing deliveries to 12,260

since the A320 began service in 1988, according to data from

UK-based consultancy Cirium, which is used across the industry.

Airbus did not immediately respond to a request for comment

on the data, tracked by aircraft supply analyst Rob Morris.
