>Did he pay and arrange her plane ticket for her?
Not required to do, they can monitor all phone lines because they use SIP over the internet one way or another. It is not hard to pick the proper flight due to that and her known schedule or to survey the plane tickets with their sources in abc agencies. Probably only a few flights out of an airport. Not like 911 where they guessed that building 7, which is one out of over a million NYC buildings, would collapse.
