Gains in the U.S. dollar against the euro did little to stem the slide in U.S. visits to Europe this summer, according to Donald N. Martin & Co., which tracks trends in European travel.
In fact, the drop-off, estimated at about 4%, is the first decline in U.S summer travel to Europe since 2002.
So who are the people filling transatlantic flights?
This summer it was a boost in Europeans traveling to the U.S.: Martin reported a 21% rise in European visits to the States in May alone.
But it is unclear how long that trend will last, as economic woes begin to loom overseas.
On a brighter note, lower oil prices may result in better airfares for the coming off-season.
