Atlanta - Delta Air Lines postponed the debut of its Airbus A220-100 to February 7 due to the partial government shutdown in the United States.

Delta Air Lines has received the first of 75 Airbus A220 on order in October 2018. The US carrier was planning to put its first Airbus A220 in service on January 31st on routes from New York La Guardia to Boston and Dallas-Fort Worth.

But the partial shutdown of the U.S. government forced the airline to postpone the debut of its Airbus A220 by one week. Because the FAA units who were tasked for the operational certification of the aircraft couldn't start this job before the planned debut date of the plane.

When an airline puts a new aircraft type in service, it must be approved by the FAA for various aspects including pilot training, maintenance, and the physical verification of the aircraft and its equipment, before entering into service.

Delta said that its operations wouldn't be affected by this delay. The mentioned routes will be operated by other aircraft types during this period.

The airline is the launch customer of the Airbus A220 in North America and has so far taken delivery of four units.

The U.S. government has been temporarily reopened on January 26.
