Do you have any tips for my flight to Thornton?
Depending on where you're coming from, your flight to Thornton could be as easy as pie or it could drag on forever. Here are some tips that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • First and foremost, put in your passport, important documents, cash and medications. Next, you'll want some entertainment to while away the time. A juicy novel and a phone crammed with your favourite movies are good options. If you hope to take a short nap, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, squeeze in a few toiletry items to ensure you touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, spray paint and fireworks. Sports equipment like ski poles, and items that could harm other people, such as guns and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • Choose comfort over style. Prepare for changes in temperature by layering up, and wear flat, enclosed footwear like sneakers.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-distance flights. Reduce the risks by staying hydrated, keeping your lower limbs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Thornton?
Being prepared before your flight can make your getaway to Thornton quick and painless. We've compiled some handy hints for a swift journey past security:

  • Be sure to have your travel documents and ID handy. They'll be the first things you'll be asked to show at security.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your tablet and phone, are also required to be scanned.
  • Can't travel without your favourite perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to have to remove them when going through security. Boots and other heavy shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, check them in.
