Are Airline Credit Cards Worth It?

Airline credit cards are often pushed to the back burner in favor of cards with transferrable rewards currencies. After all, cards like the Chase Sapphire Reserve® and the Capital One Venture X Rewards Credit Card not only provide flexibility when it comes to redeeming points, but they also tend to offer lucrative welcome bonuses as well. These cards allow holders to transfer points to various airline or hotel rewards programs, or even to redeem them for cash back.

So why would anyone get an airline credit card? Because they still have benefits that can make them worth applying for. Here are some of the pros and cons of the tool, plus other things to consider when you're trying to determine if airline credit cards are worth it.

For all the potential negatives, airline credit cards have definite positive attributes and some advantages over cards earning transferrable rewards currencies.

Hefty welcome bonuses

For starters, airline credit cards sometimes offer big welcome bonuses that can give your frequent flyer account a nice boost. Here's the current offer on the AAdvantage® Aviator® Red World Elite Mastercard®: Earn 50,000 AAdvantage® bonus miles after making your first purchase and paying the $99 annual fee in full, both within the first 90 days. That’s a tempting offer if you want to give your AAdvantage miles balance a quick bump with an easy spending requirement.

Travel-specific perks

Airline credit cards also offer perks that flexible rewards programs don’t, like the ability to earn elite-qualifying miles with your airline of choice.

Head start on elite status

Delta and Southwest both have credit cards that allow you to inch your way closer to elite status via credit card spending.

Delta Air Lines

• Delta SkyMiles® Reserve American Express Card: Earn 1 Medallion Qualification Dollar (MQD) for every $10 charged to the card.

• Delta SkyMiles® Platinum American Express Card: Earn 2 MQDs for ever $20 charged to the card.

Southwest Airlines

The following Southwest credit cards offer new cardmembers a substantial welcome bonus: Earn 50,000 bonus points after spending $1,000 on purchases in the first 3 months from account opening.

• Southwest Rapid Rewards® Priority Credit Card.

• Southwest Rapid Rewards® Premier Credit Card.

• Southwest Rapid Rewards® Plus Credit Card.

All points earned on the Southwest Rapid Rewards® Plus Credit Card and the Southwest Rapid Rewards® Premier Credit Card count toward earning Southwest's Companion Pass.

But Southwest isn’t the only airline to offer a companion ticket benefit. The Alaska Airlines Visa® credit card offers its $99 Companion Fare to cardholders who must meet a $6,000 minimum spend annually. The Hawaiian Airlines® World Elite Mastercard® comes with an annual $100 companion discount valid on round-trip airfare between the U.S. and Hawaii.

While the Citi® / AAdvantage® Platinum Select® World Elite Mastercard® doesn’t come with a companion pass, per se, it does offer an annual $125 flight discount when you spend $20,000 in a year. Frequent solo travelers may get even more value out of that $125 flight discount than from a companion ticket. (Annual fee: $0 intro for the first year, then $99.)

More affordable vacations

Airline credit cards are also useful in helping reduce travel expenses, if you’re OK with sticking to a specific program. Another helpful perk? Free checked bags, which come standard with most airline credit cards.

This is why the Citi® / AAdvantage® Platinum Select® World Elite Mastercard® repeatedly earns its place in travelers' wallets. If you take at least one trip a year with family, you could save upwards of $240 on round-trip checked bag fees. That more than makes up for the card’s annual fee.

Consider these cons to adding a miles credit card to your wallet.

Lack of redemption options

The main negative aspect of airline credit cards is the lack of redemption options. Since you'll only earn a single frequent flyer currency, you can only redeem miles with that specific airline and its partners. Airline award availability can be unpredictable, and if you can’t find award space within the program and have no flexibility in terms of travel dates, you might get stuck.

Risk of devaluations

Another reason why airline credit cards might not be ideal is that airlines reserve the right to devalue their programs at any moment, without notice. In the past, multiple airlines have made substantial changes to their award charts (before eliminating them completely in some cases) with no heads up. If a frequent flyer program suddenly devalues its currency, then you might find yourself with an airline credit card that isn’t quite as appealing or useful anymore.

Cards offering flexible rewards currencies hedge against this threat, because if one partner airline devalues its points, you can always transfer points to another partner airline.

Annual fees

Many airline rewards cards come with annual membership fees. Some are reasonable and cost $95 to renew every year. Others charge as much as $650 per year, as the Delta SkyMiles® Reserve American Express Card does (it could still be worth it for the right traveler, though). Terms apply.

No, you don’t need an airline credit card. There are upsides and downsides to spending on credit cards, and every individual’s circumstances will be unique. There are many types of airline credit cards, and if you look hard enough, you’re likely to find a good fit for you and your airline preferences.

However, none of them will be worth much to you if you don’t plan to fly much.

If you’re committed to flying annually, an airline credit card could be a good option for you. The benefits they provide can help you enjoy deeply discounted vacations and give you access to perks that make travel more convenient or comfortable.

Airline credit cards can be worthwhile if you make use of more than just the miles earned. If you can take advantage of added card benefits like free checked bags, priority boarding and companion tickets, you’ll likely get your money’s worth.

When evaluating the merits of an airline credit card, it’s also important to think about your travel goals and choose an airline that helps you get where you need to go. If you live in a specific airline’s hub city, getting a co-branded credit card can be a tremendous money saver.
