Thai Airways International (TG, Bangkok Suvarnabhumi) union representatives have asked the airline's board of directors to probe management's decision to codeshare with subsidiary Thai Smile (Bangkok Suvarnabhumi) the Bangkok Post has reported. The Thai Airways International Union (TGU) claims the agreement in which Thai pays for 100% of Thai Smaile's seats regardless of occupancy has led to THB500million (USD15.45million) in losses.

"We're keeping an eye on the executives who have caused damage to the company and will submit the case to the National Anti-Corruption Commission," a source told the paper.

Thai Smile currently codeshares with Thai Airways Int'l on its domestic routes from its base in Bangkok Don Mueang including Chiang Mai, Khon Kaen and Phuket, from Bangkok Suvarnabhumi to Changsha Huanghua, Chiang Rai, Chongqing, Colombo International, Hat Yai, Hyderabad International, Krabi, Luang Prabang, Macau International, Phnom Penh, Surat Thani, Ubon Ratchathani, Udon Thani and Vientiane as well as from Phuket to Chiang Mai.

Starting October 26, Thai Smile will move all operations to Don Mueang and add routes to Hat Yai, Krabi, Macau, Surat Thai, Ubon Ratchathani and Udon Thani.

Thai Airways International will then again operate A320-200s from Suvarnabhumi itself.
