As a result of COVID-19  travelling today comes with more challenges. Have a read over these valuable tips before jumping on your flight to Great Diamond Island:
  • Before you lock in a flight, see if any travel restrictions apply — in both your destination and origin. Keep informed with the latest updates by checking government travel advisories.
  • Wear a face mask even during airport screening. A TSA employee will ask you to temporarily lower your mask for identification purposes.
  • Avoid handing your boarding pass directly to a TSA employee. Rather, you should position the pass on the reader and then hold it up for inspection.
  • TSA is now allowing passengers to take one container of hand sanitizer, up to 12 oz (350 ml) in size, in carry-on luggage. This will have to be removed from your bag and presented for screening.
  • To minimize handling during screening, place personal items such as your phone, coins and keys into your carry-on rather than into the bins.
  • Transport your food items in a clear plastic bag and also put them in a screening bin. Keeping food separate from your carry-on makes it less likely that a TSA agent will need to open your bag for inspection.
