Chicago - On January 16, United Airlines has announced an order agreement with Boeing for four Boeing 777-300ER and 24 737 MAX.

The deal of $4.5 billion was finalized in late 2018 and included in the Boeing’s 2018 balance sheet, but the customer remained unknown so far. The order has brought the Boeing 777 program across the 2,000 orders and the 737 MAX program over the 5,000 orders.

United Airlines currently operates 18 777-300ER and nine 737 MAX 9. Including the new order, United has now 59 Boeing 777-300ER and 185 737 MAX family aircraft in its order book waiting to be delivered. Over 100 of those orders are for the MAX 10 variant and the 61 copies for the MAX 9 variant.

In 2018, United also placed a firm order for 13 Boeing 787-9 Dreamliner.
