TAP Portugal will operate flights to six new destinations from summer next year.
From June and July next year, the Portuguese airline will fly from its Lisbon hub to Toronto, Hungary, Bucharest, Las Palmas, Alicante and Stuttgart.
It will also increase its frequencies from Manchester and London Gatwick to Lisbon, adding two daily flights from Manchester and 11 weekly flights from London Gatwick.
In the last year, the airline has launched routes to Boston and New York JFK and introduced a fare structure offering one-way prices for long haul travel.
It is also currently retrofitting 48 aircraft with new cabin interiors, and plans to acquire A330 and A320 aircraft in the next year to support the higher frequencies of its mid to long haul routes.
