Do you have any tips for my flight to Weldon Spring Heights?
We've pulled together all the info you need to make your flight an enjoyable experience. Follow our tips and you'll be breezing through the airport and enjoying Weldon Spring Heights in no time. What to pack in your hand luggage:

  • The secret to having an amazing travel experience is to plan ahead. Start with the essentials: passport, official ID, cash and daily medications. Next, take on board items that'll help keep you occupied, like some electronic devices or a juicy novel. It's also smart to pack your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to pop in toiletries like a toothbrush, lip balm and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, blades, spray paint and flares. Sports equipment like bows and arrows, and items that could harm other people, such as pepper spray and guns, won't be allowed on board either.

What to wear on a flight:

  • Your main priority is to feel as comfortable as you can. Choose flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to take a jacket in case it gets cold in the cabin.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lessen your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Weldon Spring Heights?
As savvy travellers know, the secret is to be well prepared before you get to airport security. That way, you'll be boarding that plane to Weldon Spring Heights before you know it. Follow these helpful tips and get your trip off to a terrific start:

  • Your boarding pass and travel ID will need to be presented to airport security. Have them easily accessible so you don't have to dig around for them.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, take off anything that might trigger the alarms. Items like your belt, jacket and headphones will be required to go through the machine.
  • Your electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry, you'll be back online in no time.
  • Remember to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • It's also likely that you'll be asked to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Airlines will not allow any sharp objects in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked luggage.
