On the GOES front, yes. Regarding elites, once UA gets the IT capability to encode the BP with TT info, there's no reason why they can only encode the BP at EWR and not other airports. If the TSA can't be set up at all terminals at ORD, for example, fine. But as long as they're set up where I'm flying out of, even if I'm on a different airline, if the airline, be it AA, DL, or UA, has the ability to encode the BP, then they should always be able to, regardless of the airport.
And that stinks about international travel. Why? I hadn't heard that - I'm mostly on international travel
