British Airways is to receive its first two Boeing 787-8s in the final week of June, followed by its first Airbus A380 one week later.
The UK flag-carrier will take two 787s on consecutive dates, 26 and 27 June, while its initial A380 will arrive on 4 July.
"They will arrive around mid-morning," says the carrier. It has yet to disclose the routes for the 787s, simply stating that these will be "unveiled shortly".
Its second A380 will be delivered in September.
BA chief executive Keith Williams says the airline will be taking new long-haul aircraft at an average rate of one every two weeks for the following year.
As well as 12 A380s and 24 787s on firm order the carrier is taking six Boeing 777-300ERs. Of these 42 aircraft, 22 will enter the fleet by the end of summer next year.
Flightglobal has previously reported that both aircraft types will undertake crew training operations out of Manston airport in the county of Kent, followed by customer service trials at London Heathrow.
They will also be used for short-haul and domestic operations before being deployed on the regular network.
BA is intending to convert options for a further 18 787s into firm orders and place orders for 18 Airbus A350s.
