Fitch Ratings-Chicago-31 July 2017: Fitch rates the following American Airlines, Inc.'s (American; rated 'BB-'/Outlook Stable) proposed Pass-Through Trusts Series 2017-2:

--$544,644,000 class AA certificates due in October 2029 'AA'; --$252,254,000 class A certificates due in October 2029 'A'.

KEY RATING DRIVERS

Fitch issued a press release earlier today assigning ratings of 'AA' and 'A' to the American Airlines 2017-2 Pass-Through Trust Certificates. The previous release stated that the 'AA' tranche would be sized at $436.7 million and the 'A' tranche at $202.3 million. American has since upsized the transaction as referenced above, and has added seven aircraft to the collateral pool consisting of three ERJ-175s, and four 737 MAX 8s. The decision to upsize the transaction does not impact Fitch's ratings.

Base case loan-to-value (LTV) ratios in the upsized transaction are immaterially lower compared to those referenced in Fitch's initial press release. The initial base LTV for the 'AA' tranche is 39.0% as calculated by Fitch, and the initial 'A' tranche LTV is 57.4%.

The maximum stress case LTV's for both the 'AA' and 'A' tranche are roughly 0.4% points lower than the figures cited in Fitch's initial release. Fitch now calculates the maximum stress case LTV for the 'AA' certificates at 79.0% and for the 'A' certificates at 83.2%.

Fitch considers the increased size of the collateral pool to be a minor positive in terms of the affirmation factor (likelihood that American would choose to affirm the collateral pool in a bankruptcy scenario).

RATING SENSITIVITIES
Both the AA and A tranche ratings are primarily based on a top-down analysis based on the value of the collateral. Therefore, a negative rating action could be driven by an unexpected decline in collateral values. Senior tranche ratings could also be affected by a perceived change in the affirmation factor or deterioration in the underlying airline credit. The 'AA' tranche may also be downgraded to below the 'AA' category if American's IDR were downgraded to 'B-' or below as stipulated in Fitch's EETC criteria.

Fitch does not anticipate taking positive rating actions on either tranche of debt over the intermediate term.
