Do you have any tips for my flight to Mammoth?
Depending on where you're coming from, your flight to Mammoth could be completely stress-free or it could go on forever. We've pulled together some handy travel tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

  • The secret to having a hassle-free travel experience is to be prepared. First up, the essentials: passport, travel docs, bank cards and daily medications. Next, bring on board items that'll help keep you entertained, like your laptop or a thrilling novel. It's also a wise idea to pack your chargers, a quality neck pillow and a pair of earphones. Last but not least, be sure to chuck in toiletry items like a toothbrush, cleansing wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your precious Swiss Army knife, and products which are flammable or explosive, such as aerosols and strong acids, are also not allowed.

What to wear on a flight:

  • Your aim here is to feel as comfortable as you can. Pick a pair of flat, closed-toe shoes, dress in loose, breathable clothing and remember to bring a jacket in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Mammoth?
A little pre-planning before you get to the airport will help make your trip to Mammoth a piece of cake. Here are some top tips for a stress-free journey through security:

  • First things first. Your boarding pass and passport will need to be shown to security personnel. Keep them within easy reach so you don't hold up the queue.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you'll need to unplug from technology. Your phone, tablet and any other electronics must also be sent through the scanner.
  • Travelling with 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 bring it with you in your carry-on baggage.
  • Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when going through security. Boots and other heavy-style shoes are usually subjected to additional screening.
  • Knives and other sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked luggage.
