The report shows that U.S. low-cost airlines are losing their competitive advantage over major carriers.

```htmlGolden Ten Data reported on June 26 that the low-cost airline model, which has reshaped the landscape of U.S. air travel for decades, is now facing increasingly severe challenges. Meanwhile, traditional airlines are gradually gaining the upper hand by leveraging high-end cabins, lucrative frequent flyer programs, and co-branded credit cards. A report released by the U.S. Government Accountability Office (GAO) on Thursday pointed out that although the wave of industry consolidation has not ultimately weakened overall competition, many of the advantages that low-cost and ultra-low-cost carriers once relied on to disrupt the market are gradually disappearing, forcing these airlines to re-examine their business models based on "ultra-low fares".```
