"United Airlines' Q1 Loss Forecasted Due to Boeing 737 Max 9 Grounding"

United Airlines forecasts a wider-than-expected loss in the first quarter due to the grounding of Boeing 737 MAX 9 planes, but shares rise on a positive 2024 profit outlook. The company expects an adjusted loss of 35 to 85 cents per share for the quarter, with the grounding impacting non-fuel operating costs.
