3. Stick to one airline frequent flyer program. Similarly, you’ll maximize your miles if you work with a specific airline that also partners with your chosen credit card. Frequent flyer programs with airline miles offer perks for those who fly the most, including early boarding and a faster accumulation of miles for a future trip—just be sure to include your frequent flyer ID every time you book. With more miles and more rewards you will be planning your next vacation while you are still on your current vacation. At least coming home won’t be such a buzzkill!
