1979 - Four brand new Airbus A300s were purchased to serve THAI's regional routes.
Two Boeing 747-200 jumbo jets, with seating capacity of 371, were also purchased
so that THAI could offer non-stop flights between Bangkok and Europe. The company
moved into its 26-rai Head Office complex on Vibhavadi Rangsit Road, bringing all
functions and departments together for the first time.
1980 - With the arrival of the jumbo jets, THAI was now ready for Trans-Pacific services
to North America. Los Angeles became THAI's gateway city into the US. At the same
time THAI increased its operations to the Middle East.
1981 - THAI pioneered the North Pacific Bangkok-Seattle route. It expanded its route
net into the People's Republic of China by serving Canton. During that year, the
company's share capital was increased to 1,100 million baht.
1982- To better manage its growth, THAI reassessed and consolidated its fleet and
operations. Pool agreements on strategic routes were concluded with other airlines.
Though the devaluation of the Thai baht affected revenues, THAI still posted a pre-tax
profit of 26.3 million baht for fiscal year 1981/82.
1983 - THAI's Royal Executive Class was introduced on regional routes, setting a
new standard in airline comfort and convenience. Business Class passengers enjoyed
separate cabins, roomy armchair seating, lounges and privileged services. The airline
broadened its focus into related industries and bought equity in Bangkok Aviation
Fuel Services Limited (BAFS), Royal Orchid Hotel and the Airport Hotel.
1984 - THAI's efforts to promote provincial destinations in Thailand intensified.
Chiang Mai, already linked as an intermediate stop on Hong Kong flights, was serviced
with daily turnaround flights from Bangkok. Phuket and Hat Yai were added as intermediate
stops on the Singapore route.
1985 - A new Maintenance Centre at Bangkok International Airport was built, enabling
THAI to perform heavy maintenance on its wide-bodied aircraft in Bangkok. The facility
was later expanded to a three-bay hangar able to accommodate two 747 jumbo jets and
a narrow-bodied aircraft simultaneously. That year also saw the opening of THAI's
(cargo Village), one of the largest cargo facilities in Southeast Asia at that time.
Its 43,000 sq.m. Terminal handled freight shipments for THAI flights and those of
28 other airlines.
1986 - THAI launched its Stockholm flight. The middle Eastern network was further
expanded. The first branch of THAI's popular Airport Restaurant was opened at the
new Chiang Mai International Airport Terminal.
1987 - New Domestic and International Passenger Terminals were built at Bangkok International
Airport to cater for "Visit Thailand Year 1987." THAI provided 80 percent of all
passengers handling services in the new terminals. The "Visit Thailand Year" campaign
proved a huge success for the nation and the nation's flag carrier. Auckland and
Madrid were added as new destinations.
1988 - THAI and its parent company, TAC, merged into a single airline, bringing together
domestic and international air operations. With the addition of TAC's 11 aircraft,
the combined fleet now consisted of 41 aircraft. The route net comprised 48 cities
in 35 countries around the world plus a network of 23 cities in Thailand.
