Singapore-based aircraft lessor BOC Aviation has ordered 70 Airbus A320neos and 50 Boeing 737 MAX 8s for further expansion.

Boeing is seeking to withdraw its guilty plea agreement with the Department of Justice in the criminal cases surrounding two deadly 737 MAX crashes, sources familiar with the matter told ABC News.

Only four airlines will be operating MAX 8s over distances longer than 2,500 miles and most of these are Canadians flying to the Caribbean.
