9Air Co Ltd, the first budget carrier in Guangdong province offering fares for as low as 9 yuan ($1.44), will soon introduce more aircraft from Boeing Co to open more low-cost flights in China and neighboring Southeast Asian countries, a company manager said.

"We are making efforts to meet the growing market demand from domestic and overseas travelers who prefer low-cost flights," said Huang Hui, assistant general manager of 9Air Co.

The company sells tickets via its official app, on WeChat, a popular instant message platform, and through other sales channels.
