Travelers who fly often may benefit from using airline credit cards. If you're considering one, you'll want to know the benefits of airline credit cards so you can determine if this is the right type of rewards card for you. Let’s take a look at the top airline credit card benefits that you can expect.

Common airline credit card benefits

While not all airline cards are the same, they typically have similar features. By taking advantage of the perks included with an airline credit card, you may be able to improve your travel experience.

1. Bonus miles offer

For starters, most airline credit cards have a bonus miles offer, which is available to new cardmembers. You'll need to meet the minimum spend requirements within the required timeline to earn the bonus miles.

It takes time and effort to earn airline miles by flying and spending with a travel rewards card, so a new cardmember bonus offer can provide a great jump-start toward achieving your rewards goals.

2. Bonus earning categories

With bonus earning categories, you’ll earn more miles if you spend in specific purchase categories, such as buying tickets directly with the airline. Some cards even offer additional bonus earning categories such as dining or grocery spending. These bonus categories help make it easier for you to earn miles faster.

For example, with the Delta SkyMiles® Gold American Express Card, you'll earn 2x miles on Delta purchases, at restaurants worldwide (including takeout and delivery in the U.S.) and at U.S. supermarkets. Conversely, other purchases will earn 1 mile per dollar spent. Terms apply.

3. Free checked bags

While not all airline cards offer free checked bags, many do. Some cards with a lower annual fee might only offer one free checked bag, while cards with higher annual fees may offer two or more free checked bags.

Sometimes these perks are only available to the cardholder, but often, free bag perks extend to one or more additional companions traveling on the same reservation. While airline bag fees vary, most airlines charge $30 or more each way for one checked bag, so this is a valuable perk.

4. Priority boarding

Another one of the many benefits of airline credit cards is priority boarding. Airline cardholders can expect to board the plane before most economy ticket travelers. This perk may also extend to one or more companions traveling on the same reservation.

For instance, American Airlines has no fewer than nine boarding groups — but if you hold an AAdvantage credit card, you'll automatically get bumped to boarding group 5.

5. Lounge access

If you have a premium airline credit card — the kind that typically charges a higher annual fee — you may also get lounge access. Some cards offer one-time-use lounge passes while others provide unlimited lounge access.

Examples of airline cards with lounge access benefits include the Alaska Airlines Visa® credit card and the United℠ Explorer Card.

6. In-flight purchase discounts

Some airline credit cards also offer savings on eligible in-flight purchases, which may include purchases like food, drinks and Wi-Fi. If this is a perk included with your airline credit card, you can make eligible purchases during your flight and use your card to pay. You'll typically receive the savings in the form of a statement credit.

7. Travel protections

Most airline credit cards also include travel protections. While exact travel protections vary from one card to another, here are some examples of possible travel protections:

Baggage delay insurance.

Lost luggage reimbursement.

Trip delay reimbursement.

Trip cancellation/trip interruption insurance.

Auto rental collision damage waiver.

Travel accident insurance.

8. Anniversary bonus

Some airline credit cards offer an anniversary bonus. If you continue to carry your card and pay the annual fee, you may earn extra points or miles at every card anniversary. For some travelers, this perk helps to justify paying the annual fee.

9. Discounted companion ticket

Many airline credit cards also include a discounted companion ticket so you can affordably fly with a companion. Typically, cards with this benefit will include an annual companion voucher, allowing you to take advantage of a one-time discount on one round-trip companion flight per year

This is a popular and highly sought after perk. Example airline loyalty programs that offer it include the Southwest Rapid Rewards Companion Pass and the Alaska Airlines Companion Fare for Alaska Airlines Visa® credit card holders (requires $6,000 in annual spend for new cardholders).

10. TSA PreCheck or Global Entry application fee credit

Your next airline credit card might also include a credit for either the TSA PreCheck or Global Entry application fees. These government-regulated Trusted Traveler programs can make your airport experience less stressful and help you spend less time in line.

You'll need to apply and pay the application fee to use these services, and approval is not guaranteed. If your card offers a credit, you'll need to pay the application fee for one of these programs using your eligible card and then receive a statement credit as reimbursement.

11. Airline credits

Yet another one of the common benefits of airline credit cards is credit for airline-related purchases. These credits are airline-specific and typically can only be used to cover the cost of specific qualifying purchases, such as flight tickets, seat upgrades and in-flight beverages.

Often, airline credits are made available on an annual basis.

12. Elite status

With an airline credit card, you may also be able to achieve elite status faster. Many airline credit cards allow cardholders to earn elite status by spending with their card. There are usually spending requirements, so being a high spender could benefit you. Some cards may also reward you with loyalty points for spending with your card, which can also lead to elite status.

Final thoughts on airline credit card benefits

Now that you know the typical benefits of airline credit cards, you can make a more informed decision when choosing a travel rewards card. It's important to remember that not all airline credit cards are created equal and exact benefits can vary. Be sure to consider your travel and spending habits when looking at card options.
