In addition to the four "eligible" segments, you must amass a total of 1,500 BAEC Tier Points to attain BAEC Gold .You can click on the BA "Flight Calculator" at this site to determine how many Avios and Tier Points each segment would earn:



But as previously noted, any Business Class segment of more than 2,000 miles flown on any oneworld carrier will earn at least 140 Tier Points if you credit the flight to BAEC.
