Actually the conduct that got Crandall in trouble was his attempt to collude with Braniff on prices, not routes. Assuming, of course, that they did coordinate their decision, it should be noted that since neither F9 or NW are the only airlines serving the LAX/MSP market (however indirectly) their actions may appear to meet the Webster's definition, but do not meet the legal definition of collusion.
Umm... OK... Well, the last I heard, AA and BA do not have "anti-trust immunity". This means, even though they are alliance partners, they are not able to coordinate pricing, scheduling, and marketing. KLM and Northwest, on the otherhand, do have anti-trust immunity, and a relatively integrated tranatlantic system. Meanwhile, Aloha and Hawaiian Air were granted anti-trust immunity in order to protect intra-state Hawaii air service post-9/11. As part of this, they were allowed to discuss pricing, scheduling, and other things. The State of Hawaii wanted to make sure that they both didn't stop flying, so they let them discuss their competitive situation, such that both could survive.
Unless NW and F9 have anti-trust immunity, I don't think they are allowed to discuss who will serve what route. There are other precedents for this, as noted above.
Do you think UA and AA are allowed to discuss how many flights each operates out of ORD to each market?
UA to AA: Well, we want to fly 16 dailies to LGA, but in exchange, you can fly 14 dailies to BOS.
AA to UA: OK, we'll take BOS, and we also want LAX...
Of course this is not allowed. Neither is the purported discussion between NWAC and F9.
