If PA owns the airport - wouldn't they then be leasing the entire terminal to QF? Qf might (if the PA lease doesn't stipulate otherwise) sublease internally to other tenants, but PA would surely have the controlling 'ground lease'? After all, it's their dirt!
There is obviously a deal to be done and I appreciate what you say Traffic, but it seems very odd to me that a win/win can't be worked out. Joyce's bully boy attitude might be the problem??
