Ethiopian Airlines was betting Airbus’ new A350 wide-body would help it lure lucrative business-class passengers away from the likes of Emirates, but nagging delivery issues are putting Africa’s largest carrier behind schedule.

The airline won’t receive 10 new planes by the end of June as planned, with some coming as late as next year, Thomas Gabreyohannes, the carrier’s director for Germany and central Europe, said in an interview. Ethiopian is counting on the A350s to increase sales of premium tickets, similar to the boost it saw after becoming the first African airline to fly Boeing Co.’s 787 long-haul Dreamliners.
