United Airlines reported stronger first-quarter results, with profit climbing despite a $340 million increase in fuel costs. The Chicago-based carrier made tactical adjustments to navigate the higher fuel prices, which impacted operating expenses during the quarter.

Profit reached $699 million, or $2.14 a share, up from $387 million, or $1.16 a share, a year earlier. Adjusted earnings of $1.19 per share beat analyst expectations of $1.08, according to FactSet data.

Revenue rose 11% to $14.61 billion, surpassing analyst estimates of $14.39 billion. The sales growth offset the fuel cost headwinds, demonstrating the carrier's ability to maintain profitability despite industry-wide pressure from rising jet fuel prices.
