Really
Are you suggesting BBD don't have other products and services that contribute to their cash flow as well?
On Oct. 2, BBD announced the sale and options for several RJs. Since all RJs they build are well beyond that programs break even, the sales are mostly profit for their Commercial aircraft division. That firm agreement signed by Bombardier and its customer is valued at approximately $369 million USD. The value could increase to $651 million USD if all options are exercised.
I don't think you've found the ultimate answer yet, but keep looking.
I would suggest the NG and Max more directly subsidizes the B747-8, but I agree with you. A&B are much larger than BBD and benefit from more successful and established programs across many more types than BBD to soften the financial pain of losers like the A380 and A340.
Not to mention the B787, which I believe will be an eventual winner, based on present day sales.
