"United Airlines' $200 Million Boeing Setback Impacts Earnings and Summer Demand"

United Airlines' stock soared after beating first-quarter earnings estimates, reporting a loss of 38 cents per share compared to 59 cents the year prior, with a $200 million hit attributed to the Boeing 737 Max 9 grounding. The airline expects adjusted earnings to range from $3.75 to $4.25 per share for the second quarter and maintained its full-year earnings outlook of $9 to $11 per share. The stock rally also boosted rival Delta Air Lines and American Airlines, with Delta reporting an 80% earnings increase and American Airlines set to report its first-quarter results on April 25.
