British Airways has confirmed that its London Heathrow – Miami route will be served exclusively by the Airbus A380 from Sunday 25 October 2015.
The A380 will operate twice daily, replacing up to three daily Boeing 747/777 flights.
The A380 currently operates on selected flights to Hong Kong, Johannesburg, Los Angeles, Singapore, Washington, and, from April 2015, San Francisco.
There’s more information on BA’s A380 operations at ba.com. As this announcement has been made nearly a year in advance, we should sound a note of caution that further changes could be announced in the interim.
BA flights from London Heathrow to Miami are also due to move from London Heathrow Terminal 5 to 3 from 14 October 2015.
Update January 2018:
BA now operates one of two daily flights to Miami (BA208 / BA209) with the Airbus A380 in the winter season until Monday 30 April 2018. The route then operates with a Boeing 747 twice daily until Saturday 27 October 2018. The A380 then returns on Sunday 28 October 2018.
