...June 3, 2020 - With the continued steep decline in airline bookings due to the coronavirus outbreak, we expect American Airlines Group Inc. to generate a substantial cash flow deficit in 2020, but to return to positive cash flow in 2021. - American is undertaking various steps to partly offset this decline through capacity reductions, cost savings, and liquidity initiatives. - However, we believe such initiatives will be insufficient to offset the effects of sharply lower demand from the impact of the virus on the company's credit metrics. - As of now, we expect air traffic to begin to recover in the second half of 2020, but any delay will prolong weakness in credit metrics. - Therefore, we are lowering all ratings, including lowering the issuer credit rating on the company to 'B-' from 'B', and removing them from CreditWatch where they were placed with negative implications on March 13, 2020. - We are also revising our recovery rating on American's senior unsecured debt to '6' from '4',...
