Analyst · Raymond James
Thank you, Daniel. Good morning to all, and thanks for participating in our first quarter earnings call.
Before we begin, I would like to extend my sincere gratitude to all our coworkers for their commitment to the company. Their continuous efforts and dedication have kept Copa at the forefront of Latin American aviation. To them, as always, my highest regards and admiration.
Once again, we're pleased to report strong financial results. Despite facing a significant headwind in January with a partial grounding of our 737 MAX 9 fleet, we were able to deliver once more industry-leading operating margins while growing capacity year-over-year. These results were driven by a continued robust demand environment in the region and our ability to maintain low ex fuel unit costs.
Among the main highlights for the quarter, passenger traffic grew 7.1% compared to the same period in 2023. Load factor for the quarter came in at 86%. Passenger yields came in at $0.14, 3.8% lower year-over-year, while unit revenue or RASM came in at $0.125, a 4.6% decrease compared to Q1 '23.
Unit costs decreased by 6.9% compared to Q1 '23, mainly driven by lower fuel, aircraft maintenance and distribution costs. Excluding fuel, Unit cost or CASM ex came in at $0.061, a 2% decrease compared to Q1 2023. As a result, Operating margin for the quarter came in at 24.2%, 1.9 percentage points higher than in the first quarter of 2023.
On the operational front, during the quarter, Copa earnings on-time performance was again recognized by Cerium as the highest of any airline in Latin America. In fact, Copa's Q1 on-time performance, averaging above 90% was the highest of any carrier in the Americas and amongst the highest in the world.
I would like to take this opportunity to recognize our more than 8,000 coworkers who day in and day out deliver a world-class travel experience to our customers. Their contributions are key to our success.
Turning now to our network growth plan. As we mentioned in our previous call, we expect to start 3 new destinations next month. Raleigh Durham in the U.S, Anapolis in Brazil and Tulum in Mexico. I'm glad to comment that early bookings are coming in at healthy levels, and we expect these routes to have a solid start. With these additions, we'll serve 85 destinations in 32 countries, solidifying our leadership position as the hub with the most international destinations in Latin America.
Turning now to our expectations for the rest of the year. We continue to see a healthy demand environment in the region. And as you saw in our earnings release published yesterday, we are reaffirming our guidance for the year, which includes an operating margin within the range of 21% to 23%. Jose will provide more detail during his presentation.
To summarize, we delivered industry-leading first quarter financial results. We continue to deliver on our cost execution strategy. We'll grow to 85 destinations by this summer, further strengthening our network, the most complete and convenient hub for intra-America travel. We continue to see a healthy demand environment in the region and expect to once again deliver strong operating margins in 2024. And as always, our team continues to deliver world-leading operational results.
Finally, our business model is a solid and as relevant as ever. And our hub of the Americas in Panama is the best connecting hub in Latin America, making us the best positioned airline in our region to consistently deliver.
Now I'll turn it over to Jose, who will go over our financial results in more detail.
