Grass-fed beef bars for travel

Airport and airplane food is usually bad, especially if you are on a low-carb diet. A lot of times I just won't eat anything at all from the time I arrive at the airport until I arrive at my destination hotel or Airbnb. But I also keep a few of these grass-fed beef bars from Mission Meats with me, which, unlike beef jerky, have no sugar. They taste good and one bar curbs my hunger for a long time.
