NEW YORK (TheStreet) -- Boeing (BA) and Airbus (EADSY) are poised to take home at least 220 orders for their competing narrow-body jets at the Paris Air Show, a haul of at least $23 billion, sources briefed on the matter told Bloomberg. Already Monday morning, Garuda Indonesia has announced a tentative order for 60 Boeing jets.

The Asian carrier said it would buy 30 of Boeing's fuel-efficient widebody 787-9 Dreamliners and a further 30 737 Max single-aisle jets to expand its domestic market and launch new destinations internationally. Boeing will begin delivering 787s to Garuda in 2020, while its 737 Maxs will start arriving in 2022, Boeing said. Garuda CEO Muhammad Arif Wibowo added that the 787-9s would be used to enter the U.S. market, without providing further details.

Boeing also announced that Taiwan's EVA Airways plans to buy 777 cargo jets with a list price value of more than $1.5 billion, though customers generally get discounts.

Single-aisle models such as the 737 and A320 are the workhorses of the global airline industry, carrying about 75% of passengers. The Max is the latest version of Boeing's top-selling 737 and is due to enter service in 2017, while Airbus has scheduled the A320neo's debut for later this year. As the newest models of the widely used planes, their sales will be a key measure in the constant jockeying for market share between the world's two largest aircraft makers. 

Press conferences to unveil their orders are scheduled to begin Monday, when the Paris event formally opens.

Korean Air Lines plans to acquire 30 Boeing Maxes, along with 30 A320neos, sources have said. Airbus has also secured a deal from General Electric's (GE) aircraft leasing arm, GE Capital Aviation Services -- aka GECAS -- for 60 A320neo jets, doubling its commitment to the new plane. Separately, Airbus announced that Air Lease Corp. has bought additional planes, adding three A320 single-aisle jets, one slightly larger A321 narrow body, and one A350-900 long-range plane.
