Do you have any tips for my flight to Roundup?
If you're not prepared, airports and flying can be daunting. But don't hit the panic button just yet. Follow these helpful hints and enjoy a comfortable start to your getaway in Roundup. What to pack in your hand luggage:

  • Air travel can be a pleasure if you pack the right things. First of all you'll need basic toiletries, such as deodorant and a toothbrush, a fresh change of clothes and a few magazines. Next, find a spot in your bag for your phone, tablet and chargers, your important medications and maybe a cosy neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp or pointed objects lurking in one of the compartments of your carry-on luggage. Other restricted items include flammable or explosive products, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your number one priority when deciding what to wear during your flight. Loose, breathable clothing is a smart option, as are flat, slightly roomy shoes.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To reduce your risk on board, drink plenty of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Roundup?
The answer is simple — be organised. We've rounded up some helpful hints for a speedy trip through airport security. Look out Roundup, here you come:

  • Your travel ID and boarding pass will need to be inspected by airport security personnel. Have them close by to avoid fumbling around for them.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might set the alarms off. Items such as your belt, jacket and earphones need to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online in no time.
  • Want to bring along your favourite perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on luggage.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be asked to remove them when going through security. Big boots and other heavy-style shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed in the cabin.
