An interesting fare imbalance

In researching fares for our UK site, we found another interesting discrepancy between flights from Europe to the U.S. vs. fares from the U.S. to Europe. Let's say you were looking for a very last minute fare from London to Boston. You could find seats at the time of writing for the USD equivalent of $684 round-trip on United and perhaps even less on Virgin (that would be leaving tomorrow, Mar 24). But the last minute flight from Boston to London, same dates, would set you back anywhere from just over $1000 to well over $2000 round-trip. Interesting, and another reason perhaps why fares are so high from the U.S. to Europe: seats are being offered to Europeans for less than they are to Americans. Check out Virgin Atlantic's "late deals" page for other examples and do your own price comparisons in the opposite direction.
