Boeing grew its backlog by 83 aircraft and delivered 108 aircraft in the first quarter of this year.
The manufacturer says of the 108 aircraft delivered, 86 were 737s, three were 767s and 19 were 777s.
Its 737 deliveries were down from 91 during the same period in 2009, which is believed to be attributable to at least five Continental Airlines narrowbodies awaiting Koito seats before delivery.
Boeing says the 737 line is still running at 31.5 aircraft per month, and there is "not a one-to-one correlation between producing and delivering".
In the first quarter, Boeing recorded 100 new orders for aircraft, along with 27 cancellations, including 10 787s from Air Berlin and four 737s and three 777s from undisclosed customers.
By comparison, Airbus recorded 60 net orders and 122 deliveries in the first quarter.
Boeing anticipates delivering between 460 and 465 aircraft in 2010.
