Flight Details Brussels to Dublin
The long haul UA998 service had made an on-time departure out of Brussels Airport (BRU). The aircraft departed Brussels at 1130 local time this morning.
The United Airlines 787 had proceeded normally in preparation for the transatlantic crossing. It had transited the mainland United Kingdom before flight crew made the decision to divert.
Flight crew initiated the northerly diversion to Dublin from a point near the southern Irish coast. They then carried out a descent from cruising altitude FL360 (36,000 feet).
The aircraft entered a holding procedure to the west of Dublin at FL150, presumably to enable fuel dumping prior to the unscheduled landing.

Having exited the holding pattern United flight UA998 is now setting up its approach to the diversion airport of Dublin (DUB).
The aircraft has continued under normal squawk for the diversion and approach today.
