The Monthly On-Time Performance Report – May 2024

May 2024 marked a welcome return to bustling skies, with more people traveling for the summer season. The latest report provides a striking view of the global scene, revealing variations in performance among regions.

Aeromexico continued its ascent in May, leading the global airlines for the second time with an OTP of 86.75%. Although the global leader came from Latin America, the region experienced a 35% increase in flight cancellations, which led to a minimal decrease in OTP for the top-ranked airlines.
