Although we shouldn't need to explain this one at this point, we'll say it anyways. According to Dr. Midani, wearing a mask is the most effective way to keep yourself and others safe while travelling home for the holidays. "The most important thing is wearing a mask," Dr. Midani stressed to POPSUGAR. "Wearing a mask is the thing that's going to get us out of this. It's going to protect everybody." For most public transportation services, masks are not optional, and you will be kicked off of your flight, bus, or train ride if you don't comply with the rules. Keep your mask on for the entire duration of your travel time.
