NEW YORK (S&P Global Ratings) June 6, 2022--S&P Global Ratings today raised its issue-level rating on American Airlines Group Inc. subsidiary American Airlines Inc.'s (American's) 2016-1 Class A enhanced equipment trust certificates (EETC) to 'BB+' from 'BB', lowered its issue-level rating on American's 2013-1 Class A EETC to 'B-' from 'B', and affirmed its issue-level ratings on other American EETCs (including those originally issued by US Airways Inc., since merged into American). Stabilizing market values for some aircraft models and scheduled amortization resulted in improved collateral coverage for the 2016-1 Class A certificates. Conversely, collateral coverage for the 2013-1 Class A, which is secured by Boeing 777-300ER widebody planes, weakened, resulting in our lowering the issue-level rating to 'B-' from
