Star Alliance partners Continental Airlines and Greek carrier Aegean said on Monday they started code-sharing on flights between New York and Athens.
Pending government approval, Aegean will also codeshare on Continental flights from New York to Paris and Rome, offering improved access to Greek leisure destinations.
"Aegean Airlines continues to expand its codeshare strategy across the world. Thanks to this new partnership with Continental we can now offer Greek passengers a great travel solution to New York," Aegean's chief executive Dimitris Gerogiannis said in a statement.
Members of frequent-flyer programmes will be able to earn and redeem mileage anywhere on either airline's global route network, the carriers said.
Aegean, which has agreed to merge with privatised local rival Olympic Airlines pending EU approval, became the 28th member of Star Alliance in June this year, completing the integration process after its acceptance as a future member in May 2009.
