"She also said she had the impression that European airlines were getting cold feet about an accord."
Reading the above entire article again gave me some new insight.
The other Eoropean airlines getting cold feet at a deal tells me that KL,AF,LH etc. are afraid of opening up LHR and BA possibly getting US anti trust immunity for Oneworld.
As things stand now KL,AF,LH etc. etc. etc. all have open skies and US anti trust immunity and thus have a very strong advantage vs. BA and Oneworld. So it is not to their real advantage for there to be a US/EU openskies now or ever.
At least thats the way I see it.
