Frontier Airlines has extended its partnership with Barclays to offer its small business customers the Frontier Airlines MasterCard BusinessCard. The BusinessCard offers 12,500 bonus miles upon activation plus one mile for every dollar spent on regular purchase and two miles for every dollar spent on Frontier Airlines purchases. It offers simplified expense management and spend tracking features with a credit line up to $50,000. The annual fee is only $49. As an added benefit, those who make more than $60,000 in purchases this year within the 12 credit card statement cycles (January to December), will automatically be upgraded to elite Ascent status in the EarlyReturns program.
