Sell your car rental gift cards for cash
Travel credit is the least liquid gift card category by a wide margin. It only turns into value if a trip happens on those dates, at that price, through that brand — and plans move more often than balances do.
Because that credit is harder to resell and slower to verify, rates here run a little below retail: 75% of the verified balance, on cards up to $1,500. Every card in this category is checked by hand rather than by script.
Pick a brand for its exact rate and a calculator that prices any balance instantly. If the verified figure comes back different from what you entered, you see the corrected offer before anything is sent.
