Do you have any tips for my flight to Tri-City?
If you're not prepared, airports and flying can be a real challenge. But there's no need to panic. Follow these useful tips for a hassle-free start to your getaway in Tri-City. What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you bring the right things. Firstly, you'll want a few toiletry items, such as deodorant and a toothbrush, a spare change of clothes and a good read. Next, find a spot in your carry-on bag for your phone and charger, your medications and perhaps a cosy neck pillow as well. Last, but definitely not least, be sure to bring your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and gasoline, are also restricted.

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on your flight. Loose, breathable clothing is a sensible option, as are flat, enclosed shoes.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Tri-City?
A little pre-planning before you get to the airport will make your getaway to Tri-City quick and painless. We've compiled some useful tips and tricks for a swift journey past security:

  • Your travel documents and passport will need to be presented to airport security. Keep them at hand so you don't have to dig around for them.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that might set the alarms off. Items such as your coat, belt and earphones need to go through the machine.
  • For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic devices must also go through the scanner.
  • Can't travel without your favourite hand and nail cream? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can bring it with you in your carry-on luggage.
  • It's also likely that you'll need to remove your shoes for scanning, so wearing slip-on sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed in the cabin.
