What is economy B on Delta?

Fare class B is a revenue fare/booking class of service that is marketed as Main Cabin on Delta Air Lines mainline and code share flights. This fare class is considered a full fare ticket that is eligible for complimentary upgrades.



On Delta Air Lines, the B fare class is a specific revenue code that represents a Full Fare Main Cabin (Economy) ticket. This is one of the highest and most expensive tiers within the economy cabin, often sold when a flight is nearly at capacity or when a traveler requires maximum flexibility. Because it is a "Full Fare" ticket, passengers in the B class are often eligible for instant or high-priority upgrades to Delta Comfort+ or First Class for SkyMiles Medallion members. In 2026, booking a B fare also guarantees a high "earning rate" for SkyMiles and Medallion Qualification Dollars (MQDs), making it a popular choice for corporate travelers who need last-minute flights but still want to maximize their elite status progress. While the in-flight experience (seat and meal) is the same as any other Main Cabin ticket, the "hidden" benefits are the ability to change or cancel the flight with minimal or no penalties, providing a "safety net" for high-value passengers who have unpredictable schedules.
