Edinburgh Airport is Scotland's busiest, serving over 12 million passengers every year.

Edinburgh Airport (EDI) is significantly busier than Glasgow Airport (GLA) and has held the title of Scotland's busiest airport for over a decade. As of the full-year data for 2025 and projections for 2026, Edinburgh Airport handles approximately 15.5 to 16 million passengers annually, reaching record-breaking highs following its acquisition by the VINCI Airports network. In contrast, Glasgow Airport typically handles between 7.5 and 8.5 million passengers. While Glasgow was historically the dominant hub in the late 20th century, Edinburgh has pulled ahead due to its massive success in attracting low-cost carriers like Ryanair and EasyJet, as well as a wider array of long-haul international connections to North America and the Middle East. Edinburgh serves as the primary gateway for tourism and international business, while Glasgow remains a vital hub for domestic UK travel and charter flights. The gap between the two has widened in recent years, with Edinburgh now serving nearly double the passenger volume of its western neighbor.

The busier airport between Glasgow and Edinburgh is Edinburgh Airport (EDI).
