FARNBOROUGH, U.K. — Polish flag carrier LOT Polish Airlines is close to ordering as many as 60 Airbus A220 jets to renew its aging Embraer E-Jets, according to Bloomberg news agency. The airline is reportedly in advanced talks with Airbus.

The order announcement is expected during the  Farnborough International Airshow this week. An order for 60 Airbus A220 jets would be valued at around $2.1 billion, but discounts are common in such large orders. Airbus' A220 is a 100 to 150 seats small jet intended mainly for regional routes.

LOT Polish Airlines has historically been a committed Boeing customer. Its current fleet of 80 aircraft consists of Boeing 737-800s, Boeing 737 MAX 8s, 787s, and regional jets from Embraer and De Havilland.

Boeing, however, is currently struggling with B787 quality issues among a number of other problems. The 737 MAXs suffered a lengthy grounding following two fatal crashes, and its new groundbreaking widebody jet program B777X is behind schedule.
