United Airlines executives warned of economic uncertainty during their earnings call with investors on Wednesday.

United Airlines forecast lower-than-expected profit for the current quarter on Tuesday and warned of downside risks to its full-year outlook if the U.S. economy slips into a recession.

The airline said it is leaning into its business catered toward wealthier consumers, including premium seating and travel to international destinations, as those spenders appear relatively unfazed by economic storm clouds.
