Airbus said it delivered 389 aircraft in the first half, confirming a figure first reported by Reuters on Friday.
Boeing reported a 37pc drop in deliveries for the first half on Tuesday, due to the grounding of its best-selling jet in the wake of two fatal crashes.
Reuters reported last week that the first-half total of 389 aircraft would put Airbus on course to beat Boeing in 2019, but leave it with a record production task in the second half amid continued industrial snags at a Hamburg plant.
Les Echos reported on Monday that Airbus was shaving an internal delivery target, while maintaining its published guidance of 880-890 aircraft for 2019.
Airbus posted 88 net orders for the first half, easily outpacing Boeing which had a negative net total of 119 aircraft because it had more cancellations than orders during the period.
The European company was ahead on orders of narrow-body jets such as the newly launched A321XLR, which got its commercial debut with a stronger than expected tally at last month's Paris Airshow, but remained behind on larger wide-body models.
Airbus posted 123 net narrow-body orders in the first half, compared with Boeing's minus 180, while Boeing won the wide-body category with a positive total of 61 orders against Airbus' negative tally of 35 wide-bodies after cancellations.
The figures do not include a surprise letter of intent for 200 Boeing 737 MAX planes announced by British Airways owner IAG at last month's Paris air show.
