Turning to the balance sheet. We ended the quarter with approximately $7.1 billion in total available liquidity. As we noted on our January 10 investor update, due to the uncertainty of the return of service of the MAX and our commitment to our $7 billion liquidity target, we arranged an additional revolving line of credit to provide the company with increased borrowing capacity of up to $400 million. We don't have any present intention to borrow any amounts under this facility, which matures in September 2020, with an optional extension to December 2020.
