Some travel cards provide a free checked bag, which can help you save money if you frequently travel and check a bag. Checked bag fees usually cost about $30 per flight, so you can pay about $60 for each round-trip flight.

Travel cards that provide free airport lounge access can also help consumers save money because those lounges often have free snacks and drinks, so you don’t have to buy an overpriced sandwich from an airprot kiosk.

Another important perk is that travel cards often provide free travel insurance and reimbursement in case something goes wrong. This can often help you recoup funds if your flight gets seriously delayed or canceled.
