NEW YORK (S&P Global Ratings) Nov. 15, 2017--S&P Global Ratings said today that its 'BB+' issue-level rating and '1' recovery rating on American Airlines Inc.'s $1.25 billion secured term loan due 2023 are unaffected by the company's recent amendment to reduce the facility's pricing. The loan is secured by takeoff and landing slots at Ronald Reagan Washington National Airport and New York's LaGuardia Airport and certain other assets.
