Frequently asked questions

Can I cancel my flight booking to Tri-Cities due to COVID-19?
Our handy Customer Service Portal is your one-stop shop for almost every travel question, including about flight changes related to COVID-19. For greater peace of mind, we suggest reading through the terms and conditions of your chosen airline before booking your tickets.

What are some of the general tips for travellers to Tri-Cities during the COVID-19 outbreak?
The COVID-19 outbreak may have changed the way we travel, but it hasn't dampened our enthusiasm for exploring. Here are a few tips on how to cope with the new challenges of travelling:
  • Before locking in your flight, see if any travel restrictions or bans apply — in both your origin and destination. Get the latest updates by reviewing government travel advisories.
  • When you pass through airport checkpoints, do not remove your face mask. You will be asked to lower it briefly for ID purposes. Travellers who refuse to wear a face mask may be fined and denied entry.
  • Avoid handing your boarding pass (electronic or paper) directly to a TSA employee. Rather, position the pass on the reader and then hold it up for the agent to visually inspect it.
  • You are now allowed to take one container of hand sanitizer up to 12 oz (350 ml) in your hand luggage. This will need to be taken out for screening.
  • Empty your personal items from your pocket, like your small change and phone, and place them in your carry-on rather than into bins. This will minimize handling during screening.
  • If you're bringing food through security screening, put it in a clear plastic bag and then into a scanning bin. This lessens the likelihood that a TSA agent will need to handle your food container or carry-on bag for closer inspection.
