The number of US citizens travelling internationally increased to 23 million during the first five months of the year.
The US Office of Travel & Tourism Industries reports that outbound travellers increased by 4.3% compared to the same period in 2011, with Central America seeing the largest increase of 15% to 1 million travellers.
Outbound travel to overseas destinations increased by 8.6% to 11.2 million passengers and travel to North American destinations increased by 0.5% to 11.9 million during the period. Travel to Mexico decreased by nearly 1% to 8.5 million.
"The fact that travellers will take to the air this summer both domestically and in record numbers beyond our borders underscores the value airlines are delivering to customers," says industry body Airlines for America (A4A).
A4A expects 26.8 million passengers, or about 13%, on US airlines to travel on international flights from the end of May through the beginning of September. This is up about 2% from 2011.
