United 787-9 plagued by faults (simpleflying.com)

United Airlines' new Boeing 787-9 with the Elevated Interior suffered repeated technical faults on its flagship San Francisco-Singapore route, forcing multiple cancellations and a return to Boeing for repairs. The aircraft, N61101, was grounded four times before Boeing replaced both TCAS antennas, and it reentered international service in late July. Other Elevated 787-9s also experienced maintenance issues, leaving United with only one of the subfleet in service at one point in May.
