Common Fare Class Questions
Y class is full-fare economy. It offers maximum flexibility with free changes, full refunds, and 100% mileage accrual. It's the most expensive economy fare but provides the best benefits.
Both J and C typically represent business class. J is more commonly used internationally, while C is often used by some airlines. Both usually offer the same cabin service, though fare rules may vary.
Mileage accrual varies by airline and frequent flyer program. Generally, Y class earns 100%, while discounted classes (B, M, H) earn 50-100%. Deep discount classes (K, L, T) may earn 0-50% or nothing.
