Frequently Asked Questions
Is 'milla' (mile) the same as 'kilómetro' (kilometer)?
No, they are different units of distance. One 'milla' is significantly longer than one 'kilómetro' (specifically, about 1.6 kilometers). Most of the world uses kilometers, so be ready to convert if you are traveling!
Why do loyalty programs call their points 'millas'?
The concept started with airline frequent flyer programs, where you earned points based on the physical distance (miles) you flew. Even when credit cards or other companies offer points, they often keep the original name 'millas' for tradition.
