RESTRUCTURING

The following table shows the balances and activity for restructuring charges:

(in millions)	Lease Restructuring
Liability as of January 1, 2018	$	237
Payments	(54		)
Additional expenses and other	1
Liability as of September 30, 2018	$	184

Restructuring charges primarily include remaining lease payments for permanently grounded aircraft related to domestic and Pacific fleet restructurings. The domestic fleet restructuring involves replacing a portion of our 50-seat regional fleet with more efficient and customer preferred aircraft and replacing older, less cost effective B-757-200 aircraft with B-737-900ER aircraft. The Pacific fleet restructuring resulted in the 2017 retirement of the B-747-400 fleet, which is being replaced with smaller-gauge, widebody aircraft to better match capacity with demand.
