Flights are the hardest category to get cashback on

If you're saving up to fly home for the holidays or finally take a trip, it's natural to look for an app that pays you back on the ticket. The problem is that flights are usually the weakest category in any cashback program — airlines run on thin margins, so the apps and portals that pay them often pay less than they do for hotels, car rentals, or everyday shopping.

You can see this pattern clearly when you compare categories inside the same portal. On Trip.com through Rakuten, for example, car rentals have paid out at a notably higher rate than flights, with 5% cash back on car rentals, 3% cash back on hotels, and 1% cash back on flights and trains at one recent snapshot (rates that change over time and vary by portal). Airfare consistently sits at the bottom of the list.

It gets more confusing on travel booking sites themselves. TripAdvisor, for instance, pays cashback through Rakuten on experiences and bookings made through its site — but cash back is not available on hotels, vacation rentals, flights, cars, cruises, theme park purchases, virtual tours, Tripadvisor Plus subscriptions, bookings paid for by Trip Cash, or bookings made within the Tripadvisor app. In other words, the flight itself is usually the one thing excluded, even when the headline percentage looks generous.

How shopping portals like Rakuten work for travel

Portals like Rakuten work by tracking a purchase after you click through their link before you book. Several cashback apps extend beyond retail into hotels, flights, and rental cars, making them valuable tools for frequent travelers, with apps like Upside and Ibotta offering rebates on travel bookings while Rakuten partners with sites like Expedia and Hotels.com for percentage-based returns.

The payout isn't always instant, either. On travel bookings specifically, cashback can take a while to post — on some portal deals, cash back is available on bookings below a certain dollar amount, and may not appear in your account until up to 90 days after travel has been completed. That's worth knowing if you're counting on the rebate to help cover next month's bills — it won't land before the trip, and possibly not for months after.

Browser extensions and gift-card apps

Tools like Capital One Shopping work a little differently. They automatically search for coupon codes and compare prices as you check out, but rewards through Capital One Shopping are issued as gift cards rather than cash, and tracking depends on retailer reporting. That makes them fine for picking up a few extra dollars on a hotel or rental car booking, but less useful if you specifically want cash back on a flight you're trying to pay off.

Travel credit cards: where the real flight rewards are

If you're trying to maximize what you get back on airfare specifically, a travel rewards credit card booked through its own portal tends to beat shopping-app cashback by a wide margin — assuming you already qualify for one and can pay it off in full. You can get 5% back on Chase Travel when you book flights, hotels, rental cars and more through the Chase Travel portal and pay with an eligible Chase credit card, such as the Chase Freedom Unlimited. Cards built specifically for travel can do even better: Chase Sapphire Preferred gives 5X points on travel purchases booked through the Chase Travel portal, meaning 5 points per $1 spent on airfare, hotel stays, car rentals, cruises, activities, and tours.

That said, booking through a card's travel portal isn't automatically the cheapest way to fly. Independent analysis has found that some independent reviews have found flights booked through Chase's portal can run higher than booking directly, so it's worth comparing before booking. A rebate on a ticket that ends up costing more than booking direct isn't really a win — it's worth pulling up the airline's own site or a flight search tool side-by-side before you commit.

Where to actually put your cashback effort

Given all that, a more realistic strategy for a gig or hourly worker booking a trip looks like this:

  • Book the flight directly with the airline or through a flight search tool, then compare that price against any cashback portal before clicking through — don't assume the portal price is cheaper.

  • Save your cashback apps for hotels, car rentals, and experiences, where payout rates are consistently higher than they are for airfare.

  • Watch the exclusions fine print. Many travel sites specifically carve flights out of their cashback terms, so check before you assume a percentage applies to your ticket.

  • Don't count on the rebate landing fast. Travel cashback can take weeks or months to post, so it's a bonus for later, not cash you can use for the trip itself.

A cashback debit card that applies to everyday spending — gas, meals, and incidentals while you're traveling — can end up being more reliable than chasing airfare-specific deals. The B9 Visa Debit Card, for example, offers up to 5% cashback on the spending categories you use the most each month, which can cover the gas, meals, and extras around a trip even when the flight itself doesn't qualify for anything.

The bottom line

Cashback apps and portals are genuinely useful for travel — just not mainly for the plane ticket. Flights tend to carry the lowest rates in any portal's lineup, and some travel sites exclude them from cashback entirely. Save the apps for hotels, car rentals, and the spending around your trip, and treat any flight-specific cashback as a small bonus rather than the reason you booked where you did.
