Delta Flight DL43 from LAX to Sydney returned after smoke was detected in the galley. No injuries reported. FAA is investigating the incident.

US-based legacy carrier Delta Air Lines has announced that it will be expanding its partnership with American fast-food chain Shake Shack, as it will be offering first-class passengers the option to pre-select a Shake Shack cheeseburger meal on select flights out of Los Angeles International Airport (LAX).

Two separate Delta widebody flights were disrupted in one day due to the detection of fumes onboard leading to emergency landings.

Delta Air Lines has faced a series of unsettling incidents recently, including smoke or haze in the cabin on two flights and a separate crash that injured more than 20 people.

Beginning today, first-class passengers on flights with a distance longer than 900 miles going out of New York-La Guardia (LGA), Atlanta (ATL), Los Angeles (LAX), and Seattle will have Shake Shack as an option.

This marks the second smoke-related issue to impact a Delta flight within a week, just two days after an Australia-bound flight returned to Los Angeles due to smoke on the plane.

Delta Air Lines Inc. will offer Shake Shack Inc. burgers to first class passengers on longer flights departing from New York’s LaGuardia Airport starting on Tuesday.
