Boeing said it won orders for 4 777-200 jets valued at $670 million from AF. The airline exercised options on the jets, which had already been accounted for in the tally of sales published by Boeing. The planes have a list price of about $167.5 million each, though airlines typically get discounts. AF will have 23 of the extended-range 777-200 planes in its fleet by the middle of 2002.
