British Airways (IAG) plans to deploy its first Airbus SAS (EAD) A380 superjumbos on flights to New York and three Asian metropolises while using Boeing Co. (BA)’s smaller 787 Dreamliner to develop new destinations in emerging markets.

BA will take delivery of 12 525-seat A380s starting next year and is looking at using the double-deckers on high-density routes from London’s Heathrow airport to Hong Kong, Beijing and Singapore, as well as on its busiest trans-Atlantic service.

“We’ll use bigger aircraft for routes with enough traffic density and restriction on slots,” Enrique Dupuy, chief financial officer at BA parent International Consolidated Airlines Group SA, said in an interview in London. “You can’t increase your frequencies so you bring more and bigger planes.”

British Airways will generally use its A380s on “very well-known routes,” Dupuy told Bloomberg Television. The London-based company will be the third European carrier to employ the world’s biggest passenger plane, after Air France and Deutsche Lufthansa AG, which have contracts for 12 and 17 of the jets respectively.

Deployment of the 24 Dreamliners that BA has on order will seek to exploit the carbon-fiber plane’s reduced unit costs, which make it suited to lower-density routes and adding fresh locations, Dupuy said in the interview yesterday.

“The 787 will be about opening new destinations in the east, in Asia specifically,” the executive said. “It’s an under-served market for IAG and we are going to work intensively in recovering our position.”
