Adds new orders from Tuesday

FARNBOROUGH, UK, July 21 (Reuters) - Airlines have unveiled nearly 300 plane orders so far at the Farnborough Airshow in the United Kingdom, with Boeing BA.N taking a slight lead over European rival Airbus AIR.PA in the race to seal deals.

However, industry sources said they expect dealmaking to fall short of some ambitious expectations of 800 aircraft or more, as planemakers continue to grapple with supply-chain constraints and production bottlenecks.

Below are the key deals so far.

SMBC AVIATION CAPITAL

Boeing and SMBC Aviation Capital announced that the global aviation finance platform and lessor has ordered 100 737 MAX airplanes, including 60 737-10 and 40 737-8 jets.

RIYADH AIR

The Saudi carrier exercised options for 28 Boeing 787 Dreamliners from an order placed in 2023, converting 20 of those aircraft to the larger 787-10 variant.

PHILIPPINE AIRLINES

Boeing announced a new order for up to 20 787-10 Dreamliner widebody twinjets from Philippine Airlines, consisting of 15 firm orders and five options.

OTHER DEALS

Japan's Skymark Airlines has shaken hands with Aviation Capital Group to lease seven Boeing 737 MAX 10 narrowbody twinjets, with deliveries beginning in 2028.

The first Airbus order of the show came in the form of a commitment for two more H135 helicopters from the UK's National Police Air Service. Deliveries are expected in 2028.
