Ryanair

Ryanair consistently holds the crown for Europe's largest budget airline, boasting an unparalleled network of routes connecting numerous cities. Their relentless focus on cost-cutting allows them to offer incredibly low base fares, but passengers must be prepared for a no-frills experience and potential extra charges for everything from baggage to boarding passes. Recent improvements in customer service and punctuality have solidified their position as a top choice for budget travelers, despite the sometimes-strict policies. Ryanair's sheer scale and operational efficiency make it a formidable force in the budget airline market.
