THAI Smile Air, Thai Airways International (THAI)'s new sub-brand carrier, will start its first ever flight from Bangkok to Macau on July 1, local media reported on Sunday.

The airways' first route to Macau will operate two flights daily, and ticket selling is scheduled for April. The passenger load is expected to reach over 70 percent per flight, said Chokchai Panyayon, THAI Executive Vice President for Strategy and Business Development.

THAI President Piyasvasti Amranand said the new carrier is positioned to be a light-premium sub-brand of THAI, offering passengers another option for flight services.

The airline's image will be based on a trendy, friendly and worthy concept, different than the general concept of other low- cost airliners, Piyasavasti added.
