You cannot bring a full Coke can through airport security in your carry-on luggage due to the TSA's "3-1-1" liquids rule, which restricts containers to 3.4 ounces (100ml) or less. A standard soda can is 12 ounces, meaning it will be confiscated at the checkpoint. However, there are two ways to get a Coke can onto your flight: you can pack it in your checked luggage (though there is a risk of it bursting due to pressure or rough handling), or you can purchase it after the security checkpoint in the terminal. In 2026, some travelers use the "frozen" trick—technically, if the liquid is 100% frozen solid when it reaches the X-ray, it is permitted—but if it is even slightly slushy, it will be rejected. Most passengers find it much simpler to just buy a cold can at a terminal newsstand or enjoy the complimentary soda service once the plane reaches cruising altitude, as the hassle of trying to "sneak" a 12oz can through TSA is rarely worth the $4 savings.
In 2026, Chase remains one of the top-rated ecosystems for travel, primarily due to the Chase Sapphire Preferred and Sapphire Reserve cards. The "Ultimate Rewards" points earned on these cards are considered among the most valuable in the industry because they transfer 1:1 to high-value partners like World of Hyatt, United, and Southwest. The Sapphire Preferred is often cited as the best "entry-level" travel card for its low $95 fee and $50 annual hotel credit, which effectively cuts the cost in half. For frequent travelers, the Sapphire Reserve offers premium perks like Priority Pass lounge access, a $300 annual travel credit, and 1.5x value when booking through the Chase Travel portal. While these cards don't offer the "lifestyle" credits of some Amex cards, they are praised for their superior travel protections, including primary rental car insurance and trip delay reimbursement. For someone who wants flexible points that are easy to use without a PhD in "miles and points," Chase is almost always the strongest recommendation.
