These days, it can cost some serious cash to check your bags. While checked bag fees vary from airline to airline, they are rarely cheap. American Airlines, for example, charges $30 for one checked bag and $200 for four or more checked bags. These numbers go up for international flights. The good news is that some air miles credit cards offer free checked bags as a perk. If this perk is important to you, the Chase Sapphire Reserve and Capital One Venture Rewards Credit Card should definitely be on your radar. These cards can give you the chance to redeem your miles for airline purchases as well as accompanying fees and travel purchases like checked bags. If you consider yourself a luxury traveler, you should be selective in the travel card you select. The Chase Sapphire Reserve is one great option because it targets travelers who like to travel in style and comfort. With this card, you can cash in on a generous signup bonus as long — as you meet the minimum spending threshold within the specified period — and earn annual travel statement credits, among plenty of other perks.
