The Blue Fare on JetBlue is a basic economy option that provides affordable travel perks for passengers. Further, these cabins are classified into four different categories, and each provides premium services with significant flexibility. However, passengers always want to know the difference between JetBlue Blue vs Blue Extra to determine which is better according to their budget. While both classes provide better services at limited cost, the key differences include perks such as earlier boarding and expedited security, which are exclusive to Blue Extra passengers.
