FWIW, note that Bombardier is out of the commercial aviation market now; their only doing business jets now. BAe, now BAE Systems, is very much a defence company; the commercial side effectively went to Airbus with BAe's stake in it. Multiple aviation projects have almost bankrupt Bombardier in recent history, so I don't really see them getting back into it. And it's hard to see what BAE Systems would get out of entering the commercial aviation market.
