Base miles意思

"Base miles" is a term commonly used in the context of frequent flyer programs or loyalty programs offered by airlines. It refers to the minimum number of miles that a member must accumulate within a specific period, typically a year, in order to retain their membership status or elite status. Elite status typically comes with various perks and benefits, such as priority boarding, lounge access, and higher mileage earning rates.

For example, if an airline has a frequent flyer program with four tiers of elite status (Silver, Gold, Platinum, and Diamond), each tier might require a certain number of base miles to be earned within a year to maintain that status. If a member fails to earn the required number of base miles, they may be downgraded to a lower tier or lose their elite status altogether.

The term "base miles" is also used to distinguish the miles earned from the actual flight activity from the bonus miles that can be earned through credit card spending, partner promotions, or other activities. Base miles are typically earned at a rate of 1-5 miles per dollar spent on airfare, depending on the fare class and the airline's policies.

In summary, base miles are the core miles earned through flying that are used to determine an individual's status in a frequent flyer program.
