On Tuesday, it was the cheeseburger’s turn to be celebrated with hashtags and promotional deals.Burger joints across the US are celebrating National Cheeseburger Day with discounts, giveaways and more. With cheeseburgers as cheap as $1, fast food chains are practically begging you to grab a bite. Even airports like LaGuardia (LGA) have quick places like Shake Shack to get your burger fix. If a cheeseburger before your flight today sounds like something you need, the Transportation Security Administration wants to remind you that you’re allowed to bring it through airport security.This isn’t the first time TSA has chimed in on the kinds of food you can take through security. Sometimes the agency will request you remove snacks from your carry-on, but only as a way to help the officers in getting a clear view of inside your carry-on. If Chrissy Teigen can bring her emotional support casserole through security, you can definitely bring a burger. However, if you’re bringing along frozen goods, TSA suggests checking those items.Of course, if you’re looking to maximize your cheeseburger purchase consider using any card that gives you the best dining rewards, like the Chase Sapphire Reserve, Citi Premier® Card or the Wells Fargo Propel American Express® card (card no longer available).
