Also in 2010, JetBlue entered into interline booking agreements with South African Airways and American Airlines to facilitate luggage transfers between airlines for passengers with connecting flights on a different carrier. The agreement with American included JetBlue's 18 destinations not served by American and American's 12 international flights out of New York–JFK and Boston Logan. In addition, American gave JetBlue 8 round trips slots out of Washington National in D.C. and 2 out of Westchester, New York. In return, JetBlue gave American 6 round trips out of New York–JFK. The agreement with American Airlines has since ended according to JetBlue's website.
