British Airways will run new routes from Heathrow to Ljubljana in Slovenia and Montpellier in the south of France next summer.
Flights to Ljubljana will run Mondays and Fridays from July 15 to September 2.
The Montpellier route will run between the same dates on Mondays, Thursdays, Fridays and Saturdays.
Tickets are available now on BA’s website.
The airline is also increasing the number of flights to Nantes, Olbia and Valencia from Heathrow.
Further afield, next year BA will restart its Heathrow-Osaka route (which last operated in 1998), its Pittsburgh route (last flown in 1999), and launch the first international flights into Charleston.
Sean Doyle, BA Director of Network and Alliances, said: “We are gearing up for an exciting summer next year as we add more routes to our extensive network. We’re always developing our leisure offering and are committed to giving our customers even more choice of destinations at competitively low prices. As well as launching five new European routes in 2019, on our long haul network we’re also starting flights to Osaka, Charleston and Pittsburgh.”
