American Airlines has converted two Boeing 777-300ER options to firm orders, and upgraded a 777-200ER order to a 777-300ER.
The Oneworld carrier now has commitments for 18 777s, comprising 13 777-300ERs and five 777-200ERs, says the airline's chief commercial officer Virasb Vahidi in a letter to employees today.
"Our agreement with Boeing gives us the flexibility to adjust to the current marketplace, as well as better position American for longer-term growth in international markets and strengthen our network," says the letter.
"We continue to make great progress, and today's announcement is another example of the strides we're making in our restructuring process."
American filed for bankruptcy protection in November 2011.
The airline's 777-300ERs will be configured with three classes, feature lie-flat seats in first and business class, and will be equipped with wi-fi.
