The United Airlines Business Credit Card is one of many business card options for those in the business and travel world that are seeking a professional credit card. This card is issued by Chase and intended for business owners with good credit.

The card has 17.99% variable APR on purchases, 23.99% variable APR on cash advances and uses the Two Cycles Average Daily Balance (including new purchases) method for calculating the financed amount. There is an annual fee of $75 for the card and $25 for additional cardholders. The interest rates are a bit higher than most business cards but fairly average when compared to other reward cards.

The reward program features many great bonuses for business owners and travelers. You get one mile per dollar spent. These are compatible with frequent flyer miles. You receive 17,500 bonus miles after your first purchase. Cardholders of the United Airline Business Credit Card also receive a $25 United discount travel certificate and a free one-way, 1,000 mile, one-class upgrade certificate after their first purchase. You can earn 2 miles for every $1 spent on purchases from United. Earn bonus miles at participating restaurants nationwide.

There is a limit of 150,000 miles that can be earned per year. But if you are a Mileage Plus Premier, Premier Executive, or Premier Executive 1K member, you are exempt from mileage limitations. Earned miles do not expire as long as you earn or redeem miles at least once every three years.
