How travel rewards credit cards work: points, miles and perks

A travel rewards credit card pays you back in points or miles that are worth the most when you spend them on flights and hotels. Most of the decision comes down to two things: what kind of currency the card earns, and whether its annual fee and perks fit how often you actually travel.

Rewards are now the norm, not a niche. The Consumer Financial Protection Bureau reports that about three in four general purpose credit card accounts are rewards cards, and it groups those rewards into three main types: cash back, miles and points. Travel cards live in the last two.

Points vs. miles: what you're actually earning

Both are loyalty currencies, not dollars. The difference is who controls them.

Miles usually come from an airline co-branded card. Per the CFPB, miles earned on a co-brand card go straight into the linked airline loyalty account. From there, the airline sets what they're worth: how many miles a seat costs, and how many award seats exist.

Points usually come from a card issuer's own rewards program, or from a hotel co-branded card. Issuer points can often be used as cash back, for travel booked through the issuer's portal, for gift cards, or moved to airline and hotel partners. The CFPB notes that the value of a point varies by how you redeem it, but major issuers typically estimate it at about one cent.

That one-cent figure is a useful baseline. If a redemption gets you less than a cent per point, you may be better off taking cash. If it gets you more, the card is earning its keep.

Two categories of travel card

Travel rewards cards split into two broad groups. Neither is better in general. They suit different travelers.

Transferable points

Transferable points are the flexible option. You earn the issuer's currency and decide later whether to move it to an airline or hotel partner. The Points Guy describes transferable points as the most valuable kind of currency for this reason, notes that most transfers happen at a 1:1 ratio, and says the vast majority post instantly.

That flexibility has limits. The same guide is clear that there's no guarantee transferring will beat booking directly, and that you shouldn't treat loyalty balances as long-term investments. Ratios also vary by card and partner, so check before you move anything. Once points land in an airline or hotel program, that program controls their value from then on.

Airline and hotel co-branded cards

A co-branded card ties you to one brand. The upside is perks you feel on every trip with that brand. The downside is that your rewards are only as good as that one program.

The CFPB found that airlines and other partners have changed loyalty programs tied to co-brand cards to restrict access or raise the requirements for elite status. If your airline raises award prices, your miles buy less, and there's no second program to fall back on.

Typical perks on travel cards

Perks vary widely by card and change often. Common ones include:

1. Bonus earning on travel and dining. Higher points or miles per dollar in set categories, with a base rate on everything else.
2. Welcome bonuses. A lump of points after you hit a spending target in the first few months. The CFPB found almost one in ten dollars earned in rewards overall is tied to sign-up bonuses.
3. Statement credits. Credits toward travel, dining or other purchases. Some require you to enroll or use specific merchants.
4. Airport and travel benefits. Lounge access, checked bags, priority boarding or hotel status, mostly on higher-fee cards.
5. Travel protections. Insurance-type benefits for delays, cancellations or rental cars, which come with their own terms.

The CFPB notes that for cards with high annual fees, a key part of the value comes from these affiliated benefits, and that issuers have been limiting access to some of them to keep them exclusive. A perk you count on today can shrink next year.

Annual fees: the cost of entry

Many travel cards charge an annual fee. Experian says annual fees can range from around $50 to over $600 a year depending on the card, at the time of writing. Fees vary by card and change often.

Here's the basic test, with simple example numbers. Say a card charges a $95 fee and you'd otherwise use a no-fee card. If the travel card earns you $300 a year in points (valued at one cent each) and the no-fee card would earn you $250, the travel card puts you ahead by $50 before the fee. After a $95 fee, you're $45 behind. Credits and perks you genuinely use can close that gap. Ones you don't use count for nothing.

We walk through this math in detail in our guide to whether a travel card's annual fee is worth it. Some travel cards have no annual fee at all, usually with lower earning rates and fewer perks; our no annual fee cards section covers that trade-off.

The catch: interest and program changes

Two things can erase travel rewards fast.

Interest. Travel rewards are small next to credit card interest. CFPB research found that cardholders who carry debt from month to month pay 94 percent of total interest and fees but get less than 30 percent of rewards benefits. If you carry a balance, a rewards card is likely to cost you more than it pays.

Devaluation and lost rewards. In its review of complaints, the CFPB described issuers and merchant partners raising the number of points or miles needed for a redemption, and rewards vanishing when an account closed. Earning and burning points regularly, instead of hoarding them, limits that risk.

Who travel rewards cards suit

A travel card tends to fit if you:

• Pay your balance in full every month.
• Travel at least a few times a year and would use the perks.
• Are willing to spend some time learning how redemptions work.
• Spend enough in the bonus categories for the earning to outrun the fee.

A travel card is probably a poor fit if you carry a balance, rarely travel, or want rewards you can spend without any planning. In that case a simple cash back card may give you more real value with less effort.

Bottom line

Travel rewards cards earn points or miles that can be worth more than cash back, but only when you redeem them well. Transferable points cards trade simplicity for flexibility; airline and hotel co-branded cards trade flexibility for brand perks. Before you take on an annual fee, run the numbers with what you actually spend and the perks you'd actually use, and keep in mind that interest and program changes can wipe out the gain.
