The upgrade depends on the available space.
The airline has also set up a special check-in counter at Row B 7-8 at Suvarnabhumi Airport.
Once arriving at the airport, they can seek help from the airline's staff. Then, they will be escorted to the Royal Orchid Lounge and to the aircraft. Ground customer service staff will coordinate with the cabin crew to look after passengers throughout the flight. Upon arrival at the final destination, the station manager will provide assistance to passengers.
THAI has also coordinated with the Airline Operators Committee (AOC) to provide similar assistance to affected passengers holding airline tickets from other carriers. Relatives of affected passengers who wish to travel to visit injured family members receiving medical care at various hospitals in Bangkok are offered tickets to fly with THAI at a special fare.
THAI has waived the fee and surcharge for transporting the deceased back to their homeland.
THAI President Charamporn Jotikasthira said that since the waiver took effect on August 18, passengers requested flight changes at a slightly higher rate of approximately 20 per cent per day.
"THAI is in close coordination with the Ministry of Tourism and Sports to look after those affected by the situation, especially foreigners, in the hopes that they will understand and place confidence in the Thai Government and units in charge of the situation. Strict safety standards will be implemented in order to reassure tourists that Thailand is safe to travel," Charamporn said.
