Just to clarify the title, RAH is the one who pulled the plug on the F9 agreement. They've been working together to renegotiate the contract and apparently F9 wanted RAH to absorb the cost of fuel which BB refused. In the end, it was decided to part ways. Luckily, this only accounts for 12 aircraft out of over 200 so it shouldn't be the worst thing in the world.
Definately a hit to the DEN guys...hopefully this works out for everyone involved.
