The Chinese carrier will introduce a twice-weekly link between Tianjin and Gatwick, via Chongqing from June 25 with departures on Wednesdays and Saturdays, according to Routes Online.
The carrier is also planning to launch a four-times-weekly service via Tianjin Binhai International airport – the airline’s headquarters - to Vancouver from this summer.
Flights to Moscow are also earmarked for late June.
Tianjin Airlines will become the fourth Chinese carrier flying to the UK capital, following Air China, China Southern Airlines and China Eastern Airlines.
The planned routes are believed to begin upon the delivery of three Airbus A330-200s in the coming months.
