Below are a few tips that have worked for me when booking trips on my various travels.
1. Use Miles or Points
It goes without saying that using reward points is the one of the easiest ways to obtain free travel. If you don’t have miles or points, the quick hack is to apply for a credit card. Most travel credit cards come with lucrative sign up bonuses in order to entice you spend on the card frequently (make money from transaction fees) and pay it off after the month end (make money from interest charges and fees). IF you are responsible enough to pay off the card either in full or make the minimum payment each month, thereby allowing you to have a good credit score, you should be approved. Credit score needed is typically 700+ for a good travel card.
The best two travel cards I have found are the Chase Sapphire Reserve and Capital One Venture Rewards Cards.
