Delta Air Lines (NYSE: DAL) saw its shares drop sharply by 5.01% during Tuesday's intraday trading session, reflecting investor concerns over a proposed policy that could disrupt its key revenue streams.
The decline follows reports that a potential 10% cap on credit card interest rates, advocated by former President Donald Trump, may severely impact airline loyalty programs. Delta generated approximately $2 billion from its American Express partnership in Q3 2025, with nearly all tied to co-branded credit card spending. Experts warn such a cap could squeeze airlines' ancillary revenue, prompting fears of financial instability in the sector.
