U.S. and Romanian officials have signed an agreement that will eventually help Romanians travel to the United States without visas.
The deal, signed Monday, requires Romania to provide air marshals on commercial flights to America, and the U.S. to do the same on flights to Romania.
The goal is to prevent terrorist attacks and increase aviation security.
Delta Airlines currently flies from the U.S. to Romania four times a week. Tarom, the Romanian carrier, ended its unprofitable flights to Chicago in 2002 and New York City in 2003.
But it is expected to resume them by year's end. The agreement is one of several requirements needed for Romanians to travel to the U.S. without visas.
The two countries are close allies.
