I often tell people that the hardest way to earn frequent flyer miles is to step on an airplane. Even on the carriers that still offer you miles based on the distance you travel, you’ll only earn about 500 miles per hour you spend on an airplane. And you’ll have to spend an entire night in a hotel just to earn a few thousand points in their loyalty program.

In contrast, it takes just a few minutes to apply for a credit card that can offer you 50,000 to 100,000 points or miles as a welcome bonus. 50,000 miles is a competitive offer from an airline card or one that offers points that can be transferred to airline miles. However, the best offers will be in the 60,000 to 100,000-mile range.  With hotel points, a strong offer is one with enough points for at least two free nights in a mid-range hotel. But because hotel points are generally less valuable than airline miles, expect to receive 75,000 to 125,000 points from the best of these offers.

To receive these rewards, you’ll typically have to meet a minimum spending requirement, often $3,000 to $5,000 within three months of account opening. However, some of the most generous offers will have even larger spending requirements. Also, most cards will have an annual fee, although some are waived the first year.

Once you’ve paid an annual fee and received your welcome bonus, the last thing you’ll want to do is cancel your card. Instead, try it out for a year and see how you like its rewards, benefits and customer service. At the end of your first year, you’ll have all the information you need to decide if it’s worth keeping or not.
