COVID-19 has led to major changes to the way we travel. If you plan to visit County Donegal, these tips will help you navigate these new challenges and rules:
Research what rules and restrictions apply to both your destination and origin. It may not be possible to travel depending on local circumstances, so check before you book your flight.
You’re required to wear a face mask at the airport, including at security checkpoints. You should be prepared to lower your mask for ID verification when asked by a TSA officer.
To reduce the risk of cross-contamination, position your boarding pass on the reader yourself and then hold it up for inspection. Do not hand your pass directly to a TSA officer.
TSA is now allowing passengers to take one container of hand sanitizer, up to 12 oz (350 ml) in size, in carry-on baggage. This will have to be removed from your bag at the X-ray machine for screening.
Remove items from your pocket, such as your phone and wallet, and put them in your carry-on instead of into bins. This will minimize handling during screening.
Transport your food items in a clear plastic bag and also place them in a screening bin. Separating food from your carry-on makes it less likely that a TSA officer will need to open and touch your bag for inspection.
