I was spending way too much on airport food until I saw a flight attendant's lunchbox
I had a 6 hour layover in Atlanta last month and was about to drop $18 on a sad sandwich at the terminal. Then I noticed the gate agent next to me pull out a full meal from her bag, stuff she'd clearly brought from home. It clicked that I could do the same. Now I pack a Tupperware with a proper sandwich, some fruit, and snacks every time I fly. It costs me maybe $3 total versus airport prices. I just make sure everything is solid, no liquids over 3.4 oz to get through security. It saves cash and I eat better. What other easy airport food tricks do you guys use?
