July 27 (Reuters) - Southwest Airlines (LUV.N) on Thursday warned of higher labor costs for the year and signaled softer pricing for the current quarter, stoking worries that rising operational expenses could add to a potential hit to travel demand from strained household budgets.
American Airlines (AAL.O), United Airlines (UAL.O) and Delta Air (DAL.N) also fell between 1.0% and 1.5% premarket after Southwest's results.
The airline attributed the fall in RASM, a proxy for pricing power, to tough comparisons from a boom in travel demand last year.
U.S. airlines have reiterated resilience in travel demand, in part due to limited capacity, though concerns remain over the impact of rising interest rates on consumers' disposable income.
Surging international travel demand has also grabbed a share from domestic travel, Alaska Air Group (ALK.N) said earlier this week.
