On AA98 next week and noticed this has a chronic delay leaving ORD (for the ORD-LHR segment, NOT the TUS-ORD same flight number with different equipment)

Trying to see what else systemwide is this bad. Is this a crew inbound issue or the 772 maint issues as this is set as a converted/new cabin - no spare aircraft or flex on aircraft swaps?
