Apinan Sumanaseni, president of the national carrier, said the change of landing destinations cost THAI Bt200,000 - Bt400,000 per flight. He did not provide the number of all flights affected.
Flights were diverted to Chiang Mai, Don Muang and UTapao. Aside from the financial costs, the diversions also disrupted airline schedules.
"Weather conditions slightly affected THAI. Unable to land at Suvarnabhumi, the planes have been diverted to other airports until the conditions at Suvarnabhumi are clear. This resulted in additional fuel costs," Apinan said.
THAI also recently adjusted its spare parts control system which resulted in maintenance delays. Apinan said the problems will be solved and all schedules be resumed from today onwards.
