Counting rewards, fees, and any credits, the Frontier Airlines World Mastercard® delivers more total value, about $173 a year more for a typical spender, mostly because it earns more where you spend most, on travel and dining. Neither leans on transferable points, so the deciding factors are the welcome offer, the card network, and which everyday perks you will actually use. On the sign-up bonus, the two are currently comparable in size. Note that Southwest Rapid Rewards® Priority is running a limited-time offer above the usual amount, so that edge may not last. A welcome bonus is a one-time event, so weigh it apart from the ongoing rewards.
Pick the Frontier Airlines World Mastercard® if your spending leans toward dining, travel. Pick the Southwest Rapid Rewards® Priority if your spending leans toward gas.
