COVID-19 has resulted in huge changes to the way we travel. If you're planning a trip to Serbia, these tips will help you navigate these new traveling challenges: Before booking anything, find out if any travel restrictions apply — in both your origin and destination. Stay informed with the latest updates by checking government travel advisories. Wear a face mask during airport screening. A TSA employee will require you to adjust your mask for ID purposes. To reduce the potential of cross-contamination, position your boarding pass on the reader yourself and then hold it up for inspection. Do not hand your boarding pass directly to a TSA employee. One liquid hand sanitizer container is now allowed in your carry-on bag. It must be no larger than 12 oz (350 ml), and you'll have to remove it from your bag at the X-ray machine for scanning. To reduce handling during screening, place personal items such as your phone, keys and wallet into your carry-on rather than into the bins. Separate any food you're carrying for X-ray scanning. Food items often set off the alarm. Placing them in a clear plastic bag and into a bin reduces the need for a TSA employee to handle and inspect your belongings.
