Ninety-six million travelers flew to and from the United States in the six five months of 2014, a seven percent increase over the same period last year, according to data released today by the National Travel and Tourism Office.

International air traffic also picked up in comparison to April and May as the northern hemisphere began summer holidays.

Every month, the OTTI releases data regarding recent travel activity, including details about international air passenger traffic to and from the United States. This is the most recent month for which this information is available.

For statistics on international air traffic in May 2014, see here.

Non-U.S. citizens make up a larger percentage of passenger traffic in and out of the United States; such passengers increased seven percent year-over-year to 53 million travelers.

The number of U.S. citizens flying abroad increased 8 percent to 43 million.

U.S. carriers account for slightly more market share, 53 percent, than foreign carriers, 45 percent; however, passenger growth on foreign carriers (+9 percent) exceeded growth seen on U.S. airlines (+5 percent).

The largest markets for air traffic to and from the U.S. are Europe and Asia, which combined account for 42 percent of all international traffic.

The markets that experienced the largest growth in the first fourth months of 2014 versus 2013 are the Middle East and Central America for the second month in a row.
