旅行奖励最好的信用卡是什么？
there’s no one “best” credit card when it comes to travel rewards—or any type of rewards for that matter. that’s because everyone’s spending patterns are different and someone who travels frequently will fare best with a different travel rewards card than someone who travels maybe once a year.
免费航班所需的里程数取决于不同的因素，包括您正在使用的航空公司里程，当您旅行和其他因素时，您可以飞往和来自。美国的航班通常需要比国际航班更少。通常，在经济中的国内单向飞行中，依靠4,000到20,000英里的支出。
长途国际航班可以花费更多。计划在每种方式到达20,000到30,000英里的支出，以便更多地飞往亚洲，非洲和大洋洲的航班。  
don’t forget to consider the cost of checked bags and fuel surcharges before booking your ticket. flights booked with rewards are also often subject to government taxes and fees.
