British Airways' first Boeing 787-8 has missed its scheduled arrival date at London Heathrow after undisclosed operational matters held up the aircraft.
The UK flag-carrier confirms that it has taken delivery of the Rolls-Royce Trent 1000-powered twinjet in Seattle.
But it says "operational issues" have resulted in a "slight delay" in the arrival of the 787 at Heathrow.
BA had scheduled two 787s to arrive in the space of 24h, the first at around 10:20 on 26 June. The second was due the following day, ahead of the arrival of its first Airbus A380 on 4 July.
"We expect our first two 787s to arrive at Heathrow within the next few days," the carrier says, without giving a new date. It has not indicated the specific nature of the hold-up.
BA initially ordered 24 787s - a mix of eight 787-8s and 16 787-9s - before recently committing to take another 18. The airline is a launch customer for the stretched 787-10 with a planned order for 12.
