Chase is offering 50,000 Southwest Rapid Rewards points after $2,000 spend within 3 months of opening your account.
The ‘standard’ offer is just 25,000 points, and this limited-time doubling of the bonus expires June 29. (There have been times in the past where the big signup bonus gets pulled officially but there are still some links that remain and continue to work. I cannot say whether that will happen this time or not.)
50,000 points is worth $710 in airfare when redeeming for ‘Wanna Get Away’ fares, or $500 in gift cards.
