Citi Premier Card - This is a great card to start trying out travel award cards because of its large amount of categories to be able and spend, to earn points.
Chase Sapphire Preferred Card - This has a higher fee but if you can budget it in, they have great travel rewards that offset these fees.
Venture Rewards Capital One Card - This is a safe card to start with. Not as many rewards but zero down really helps. Does still have great travel benefits
