With new COVID-19 safety measures to follow, travel looks a little different at present. These are some helpful things to know before you jet off to Greece: Before you lock in a flight, check if any travel restrictions or bans apply — in both your origin and destination. Get up-to-date information by checking government websites. When you pass through airport checkpoints, keep your face mask on. You will be required to lower it briefly to confirm your identity. Passengers who refuse to wear a mask may be denied entry or boarding. Rather than handing a TSA agent your boarding pass, place it directly on the scanner yourself. After that, hold it up for inspection. One liquid hand sanitizer container is now permitted in your carry-on baggage. It must not be larger than 12 oz (350 ml), and you'll have to remove it from your bag at the X-ray machine for screening. To reduce handling during screening, place personal items such as your belt, phone and wallet into your carry-on instead of into the bins. Separate any food you're carrying for X-ray screening. Placing it in a clear plastic bag and into a bin reduces the need for a TSA agent to touch and inspect your belongings.
