My single favorite card for earning valuable rewards points is the Chase Sapphire Preferred Card and it currently has its best-ever public offer that lets you earn 50,000 bonus points after you spend $4,000 on purchases in the first 3 months from account opening.
But Citi Prestige earns even more points — triple, not double — than Sapphire Preferred on air and hotels. It doesn’t just earn double points on dining like Sapphire Preferred, but also ‘entertainment’ which is a broad category.
