Air miles credit cards offer a great way to build up frequent flyer miles by just making everyday purchases. They are also a great way to earn free travel and other rewards, but they often offer much more than just the ability to earn miles. Depending on the card you have, you may have access to extra features you didn't know about. Here are five ways you can get the most out of the best air miles credit cards out there.

Utilize the Concierge Service
Traveling to new places can be fun, but an unfamiliar city presents challenges even to veteran travelers. Luckily, many of the best air miles credit cards offer a free concierge service that is available 24 hours a day. You can use the concierge service for directions, restaurant suggestions, dry cleaner recommendations and much, much more. This way you won t get lost in an unfamiliar city or town and you can get some of the best dining recommendations to fully enjoy your stay.

Get In-flight Discounts
Even if you don t use your air miles card to purchase your travel fare, you can still get discounts during your flight by using your card. These discounts vary from one air miles card to the next, but if you need that beverage, meal or snack that isn t complimentary to hold you over, or you forgot your headphones or would like to purchase a blanket to make yourself more comfortable, you can most likely get a discount on these items when you use your card in-flight.

Use Airport VIP Lounges
Waiting in a loud airport terminal could test your patience, especially if you travel frequently or need to get some work done while you wait for your flight. Your air miles card might just grant you access to some of the best airport lounges around. Airport VIP lounges are generally owned and operated by the airline   Delta, United, etc.   but can offer you a luxurious waiting experience and just might include things like free beverages and snacks. Many air miles credit cards offer this automatically when you use your card to purchase your travel fare, while some may charge a small fee for access.

Use the Companion Ticket
Only the best air miles credit cards out there offer this, so see if your frequent flyer miles card provides this benefit. If your card includes this feature, you will most likely need to meet certain requirements, but generally you are granted a companion ticket once per year for a round-trip domestic airfare. Although some restrictions may apply, this is a great way to give your spouse, partner or a family member or friend a generous gift.

Take Advantage of Hidden Extras
Most air miles credit cards come with numerous hidden extras, and some of them are specifically helpful for individuals who travel frequently. For instance, when you purchase your airfare or other travel fare with your air miles card, you may automatically qualify for travel accident insurance, rental car insurance and lost luggage reimbursement. Although we hope you won t need them, these extras can come in handy in case of an emergency situation.

Additionally, many credit cards offer 24/7 roadside assistance. And although it s not related to travel, when you purchase certain products that have a manufacturer warranty, you may be privy to extended product warranty coverage.
