COVID-19 has changed how we travel, but it hasn't done away with our eagerness for exploring. Here are some tips on how to deal with travel's new challenges: Before locking in your flight, find out if any travel restrictions or bans apply — in both your origin and destination. Keep informed with the latest updates by checking government travel advisories. When you pass through airport checkpoints, do not remove your face mask. You will be asked to briefly lower it to confirm your identity. Passengers who refuse to wear a mask may be denied entry or boarding. You're no longer required to hand your boarding pass directly to a TSA officer. Rather, you should position the pass on the scanner and then hold it up for inspection. One container of liquid hand sanitizer is now allowed in your carry-on luggage. It must not be larger than 12 oz (350 ml), and you'll need to remove it from your bag at the X-ray machine for scanning. To minimize handling during screening, put items such as your wallet, phone and belt into your carry-on rather than into the bins. Separate any food you have for X-ray screening. Food items often set off the alarm. Placing them in a clear plastic bag and into a bin reduces the need for a TSA officer to handle and inspect your belongings.
