Airline industry heading for summer boom

With the approaching of the peak air transport season in summer, and the grounding of troubled B737 MAX aircraft, demand has exceeded supply in the domestic aviation market, which will lift flight ticket prices and boost the sales of carriers and their stock performance, industry analysts said.

New York investment bank Goldman Sachs shifted its overall view of China's aviation sector to positive, as it expects the valuations of the sector will be supported by growing demand.

Goldman Sachs upgraded shares of State-owned carriers Air China and China Eastern Airlines from "neutral" to "buy" on Thursday, for shares listed in the Shanghai A-share board and in Hong Kong, according to its report.
