The Southwest Rapid Rewards Performance Business Credit Card is the most feature-packed Southwest card on the market. It comes with 9,000 bonus points after each account anniversary (worth an average of $126 in travel); it offers four upgraded boardings each year (worth at least $120 in total); it grants up to 365 inflight Wi-Fi credits each year (worth $8 each). This card easily justifies its $199 annual fee for those who fly Southwest even a few times per year.
