British Airways will launch additional flights from Heathrow to New York JFK, Johannesburg, Miami, Hong Kong and Riyadh at the start of the summer schedule.
At the same time, partner Iberia will move its eight daily services to Madrid into Terminal 5 from Terminal 3 to give passengers a smoother transfer between BA and Iberia flights.

BA will offer additional shorthaul flights to its most popular destinations such as Barcelona, Brussels, Bologna, Rome, Hamburg, Paris Orly, Prague, Helsinki, Edinburgh, Glasgow and Manchester.
At Gatwick British Airways will start daily flights to Algiers, as well as services to Nice.
