My understanding from several years ago from the UAL ALPA Crew Rest Oversight Committee
CROC is that the A350 crew rest facility is illegal per 117 and most importantly our contract. DAL & DAL ALPA jointly applied for a waiver from the FAA. Our contract is far stronger for crew rest then DAL and we can prevent UAL from flying A350 unless we agree. That’s leverage! It’s a structural problem and can’t be fixed.
