Boeing has said it has "full confidence" in the safety of the 737 MAX fleet despite two fatal crashes since October and a rising number of regulators and airlines grounding the planes around the world.
"We understand that regulatory agencies and customers have made decisions that they believe are most appropriate for their home markets," Boeing said.
It adding that the US Federal Aviation Administration "is not mandating any further action at this time, and based on the information currently available, we do not have any basis to issue new guidance to operators."
Boeing delivered 95 aircraft in the first two months of 2019, up from 93 planes a year earlier, with its best-selling 737 MAX jets comprising nearly half of those deliveries.
The world's biggest planemaker won 48 net orders between January and February, beating European rival Airbus, which did not report any wins and had 99 cancellations dominated by its widebody A350-900 aircraft and the superjumbo A380.
Airbus delivered 88 aircraft in the same period, up from 65 a year earlier.
