Vietnam Airlines and Thailand’s Bangkok Airways on Monday entered a code-share agreement to give passengers convenient and seamless access to destinations in both countries.

Passengers flying with Vietnam Airlines from Hanoi or Ho Chi Minh City to Bangkok are now able to continue boarding a Bangkok Airways flight to Chiang Mai, Phuket, Koh Samui, Krabi and Chiang Rai.

Flyers only need to complete booking and check-in once with Vietnam Airlines to be able to travel with the Thai carrier.

The code-sharing also brings passengers more choices of visiting both countries, with the launch of nonstop services connecting Bangkok with three Vietnamese cities, Da Nang, Hanoi and Ho Chi Minh City.

The Bangkok-Da Nang route is operated by Bangkok Airways with one daily flight, whereas Vietnam Airlines offers six daily services each on the Bangkok-Ho Chi Minh and Bangkok-Hanoi routes.

“This code-share agreement allows Bangkok Airways’ passengers a convenient and seamless access to more destinations in Vietnam,” Puttipong Prasarttong-Osoth, president of Bangkok Airways, remarked when the agreement was announced in October.

“Likewise, Vietnam Airlines’ passengers are able to travel to well-known destinations in Thailand through our network.”

Flight routes between Thailand and Vietnam are one of the most dynamic in air networks in Southeast Asia, with the number of available seats rising 30 percent from 2016 to 2017.
