Airline fare classes go beyond economy versus business—they determine refund policies, upgrade eligibility, and mileage earning. Understanding these codes helps you make smarter booking decisions.
Fare Class Basics
Each letter represents a specific fare type with its own rules. Y typically means full-fare economy with flexibility. B, M, and H often indicate discounted economy with restrictions. K and L are usually the cheapest and least flexible.

Why Fare Class Matters
Elite frequent flyers earn more miles on premium fare classes. Upgrade availability often depends on your fare class. Cheaper fares may have no refund or change options. Understanding trade-offs helps balance price and flexibility.

Strategic Booking
Check fare rules before booking—cancellation and change fees add up. Consider slightly pricier flexible fares for uncertain trips. Basic economy fares often exclude seat selection and carry-on bags—factor these costs in.
Don’t always chase the cheapest fare. Total value includes flexibility you might need later.
