Spring Airlines, the nation's only budget carrier, is joining hands with a regional bureau affiliated to the Ministry of Railways by launching a one-hour air-train travel service for passengers in East China, the carrier told a media briefing on Tuesday.

Shanghai-based Spring Airlines released its new air-plus-high-speed-train product with Shanghai Railway Bureau on Tuesday. Passengers taking flights with Spring Airlines to or out of Shanghai can get free high-speed train tickets to the cities of Suzhou, Hangzhou, Wuxi, Changzhou and Jiaxing, which are all within a one-hour train journey from Shanghai in the Yangtze River Delta region.

According to the low-cost carrier, passengers have been able to book their trips to and from these cities through Spring Airlines online since Tuesday.
