Hola
Es un programa de Frontier Airlines.
Espero que ayude.

Frontier offers two different programs for companies of all sizes. The two programs are the Corporate Air Travel Solutions (CATS) program, for companies with enough travel spend on Frontier to make them eligible for an upfront discount, and the Best Care Business (BCB) program, for companies with lower travel spend, who would like to earn points for awards. For more information on both programs and to check your company's eligibility, please click here.

To ensure the customer receives the best price and SkillsUSA receives credit for the purchase, make sure the Best Care Business (BCB) identification number is provided during the reservation process. Online is only available at www.frontierairlines.com. It’s very easy to book flights using the two options listed below.
