We're visiting the US on honeymoon in July (San Francisco, Hawaii, New York)
Our first stop will be Chicago where we'll connect to SFO.

We're flying American Airlines, so presumably a large percentage of the flight will be Americans?

Do you think this might reduce the amount of time it takes us to get through immigration, in that most of the flight won't be foreign nationals?

We've a three-hour wait before the SFO flight but hope we won't be waiting too long at immigration. My last visit to the US in 2005 (MIA) took forever to get through.

I should be 'on the system' in terms of the fingerprint control thing but my wife-to-be has never been to the States before.

Any thoughts?
