I’ll be the first to admit that travel isn’t always cheap. While it’s possible to explore destinations like Thailand, Cambodia, and Vietnam on a budget, your expenses eventually add up even if you’re only spending $20 per day.

Since I started traveling the world full-time six years ago, I’ve used travel credit cards to collect points and earn miles. It’s helped me afford round trip flights, upgrades to business class and stays in some of the world’s top luxury hotels.

But with so many different travel credit cards out there, it’s a bit overwhelming trying to decide which one is the best option for you. Plus, there are other things to consider like annual membership fees, reward schemes and how to earn points on your purchases.
