Passengers at Bush Airport shared some of their best travel tips.
"Make sure you have everything you need for your trip - any last-minute arrangements that you need to make. If you're traveling with kids, have everything they need to be comfortable. Dress warm because it is cold outside," Briana Coleman said, who was traveling to Los Angeles.
