Indonesia's largest air carrier has informed Boeing that it wants to cancel a $4.9 billion order for 49 Boeing 737 MAX 8 aircraft. Garuda Indonesia spokesperson Ikhsan Rosan said in a statement to the Associated Press that the airline was cancelling due to concern that “its business would be damaged due to customer alarm over the crashes.”

Garuda had originally ordered 50 737 MAX aircraft, and Boeing delivered the first of those aircraft in December of 2017. The airline already operates 77 older Boeing 737 models; two of the aircraft ordered were conversions from earlier orders for 737-800s. Garuda also flies Boeing's 777-300 ER, and the company retired its 747-400 fleet in the last few years—so the airline was looking for an economical long-range aircraft to fill in gaps.
