Yes, BA has Rolls Royce engine problems, causing problems for BA. For example BA will no longer fly from DFW, however their code-share partner AA will make up the difference. That said BA added a second flight from Austin to Heathrow. I am sure Qatar will make up the difference on the lost BA flights between Heathrow and Doha. BA's problem will be getting back that LHR-DOA business after its customers are used flying Qatar.

Qantas aren’t much better.
