Frequently asked questions

Can I cancel my flight booking to Grassy Key due to COVID-19?
If you've yet to book your tickets, check the terms and conditions of the airfare you're considering. If you've already locked in your flight to Grassy Key, make use of our Customer Service Portal.

What are some of the general tips for travellers to Grassy Key during the COVID-19 outbreak?
The COVID-19 pandemic has triggered substantial changes to the way we travel. If you're planning a trip to Grassy Key, these tips will help you navigate travel's newest challenges:
  • Investigate if any travel restrictions apply to your origin and destination before booking anything. Also check if there are any conditions you'll need to follow on arrival, such as proof of a negative COVID-19 test.
  • When you pass through airport screening, keep your face mask on. You will be required to lower it briefly to verify your identity. Anyone refusing to wear a mask may face civil penalties and may also be denied boarding.
  • Rather than handing a TSA employee your boarding pass, position it directly on the reader yourself. When that's done, hold it up for inspection.
  • You are now allowed to take one container of hand sanitizer up to 12 oz (350 ml) in your carry-on baggage. This will need to be removed for X-ray scanning.
  • Remove items from your pockets, such as your wallet, coins and keys, and put them in your carry-on instead of the bins. This will reduce handling during the screening process.
  • Transport any food items in a clear plastic bag and also place them in a screening bin. Keeping your food separate from your carry-on means it's less likely a TSA officer will need to open your bag for inspection.
