Do you have any tips for my flight to Florissant?
Wherever you're jetting in from, flying can be a pleasurable experience if you've planned ahead. Take a peek at these handy tips that will get your Florissant escape started on the right note. What to pack in your hand luggage:
  • First and foremost, put in your passport, important documents, credit cards and vital medications. Next, you'll want some extra in-flight entertainment to help pass the time. A juicy novel and a tablet crammed with your favourite movies are good options. If you hope to take a quick snooze, a neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, leave some space for a few toiletry items so you'll step off the plane feeling fresh as a daisy.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have a Swiss Army knife lurking in your hand luggage. Other banned items include flammable or explosive products, such as bleach and fuel, and liquids and gels 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 on board. Loose clothing is a wise option, as are flat, slip-on shoes.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.
How to get through airport security fast when flying to Florissant?
It's all about being organized. We've pulled together some handy tips and tricks for a speedy trip through airport security. Watch out Florissant, here you come:
  • Airport security personnel first need to verify that you have a valid ID and matching travel documents before you're allowed to proceed any further. Have them ready to show.
  • The X-ray machine is up next. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronic gadgets must also go through the scanner.
  • Travelling with a new hand and nail cream? Not a 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're allowed to bring it with you in your carry-on.
  • It's also likely that you'll be asked to take your shoes off to be X-rayed, so wearing slip-on shoes is always a wise idea.
  • Sharp items such as knives and scissors are not allowed in the cabin. They'll be confiscated at security, so put them in your checked baggage.
