A lesser-known benefit offered by some credit cards is travel insurance. This feature can include trip cancellation insurance, lost luggage reimbursement, and rental car insurance, all of which can save you money when unexpected travel issues arise. Travel insurance is often an overlooked perk that comes with certain premium cards, and cardholders may not realize they have this coverage unless they take the time to read through the benefits.

In addition to travel insurance, some credit cards also offer additional travel-related perks, such as free checked bags, airport lounge access, and global entry or TSA PreCheck credits. These perks can make a significant difference for frequent travelers, but they are often only available on premium cards with higher annual fees. Reading through the card's benefits carefully can help cardholders take advantage of these often-overlooked perks, adding more value to their card usage.
