Depends. If AMR goes after AS I assume we would have a compelling case for the government. See AS does the Lion's share of our feed to our Asian gateway flights in SEA, and PDX, and they do a bunch in LAX. Without them those routes would have issues. To me that is the biggest reason DAL has.

HI is a small operation and there is little they could do about that one, but try to take the HND slot. I am sure that the lawsuit over the LGA slots will determine the outcome of DAL going after HI. (Just my guess)
