CHICAGO, Jan 22 (Reuters) - United Airlines Holdings on Monday forecast a wider-than-expected loss in the quarter through March due to the grounding of Boeing 737 MAX 9 airplanes.

The Chicago-based carrier expects an adjusted loss in the range of 35 to 85 cents a share, assuming all MAX 9 planes remain grounded through the end of January. Analysts expected the company to report a quarterly loss of 21 cents a share.

The company, however, estimates an adjusted profit of $9-$11 per share in 2024. That compares with $9.58 per share expected by Wall Street analysts. (Reporting by Rajesh Kumar Singh in Chicago Editing by Matthew Lewis)
