|Subject: USA air travel|
It may be different from Europe than from Asia but we have found that the trips within NA are much cheaper when they are booked together with our trans-Pacific ticket. If we did it separately (whether booked from over here or through a NA travel agent), the NA routes would be much higher. In fact, many friends in NA have expressed dismay that they can't get the same prices as we can get.
It's certainly worth doing a comparison.
