“Further review of the proposed financial investment, taking into account the latest public disclosure of American Airlines, has demonstrated that the investment no longer meets our objectives,” Qatar Airways said in a statement.

The news came as a relief to American Airlines executives, who have from the beginning been viscerally against the idea.

“We aren’t particularly excited about Qatar’s outreach,” CEO Doug Parker had written in a letter to employees seen by CNBC in June. “We find it extremely puzzling given our extremely public stance on the illegal subsidies that Qatar, Emirates, and Etihad have all received over the years.”

An AA spokesman said late Wednesday that “This in no way changes the course for American.”

Qatar Airways didn’t elaborate, but American’s second-quarter earnings had beaten expectations and supported its share price, making it harder for Qatar to pick up a stake on the cheap.

The state-owned carrier lost access to 18 Middle East destinations in fallout from the ongoing regional political crisis.
