Do you have any tips for my flight to Rainier?
Depending on where you're coming from, your trip to Rainier could be a breeze or it could drag on forever. We've pulled together some handy hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:
  • First of all, pack in your passport, important documents, cash and daily medications. Next, you'll want some extra in-flight entertainment to while away the time. A thrilling book and a tablet filled with your favourite shows are good options. If you hope to catch forty winks, a neck pillow and some earplugs will also be useful. Finally, squeeze in a toothbrush and some facial wipes so you'll hop off the plane looking fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have sharp or pointed objects hiding in your hand luggage. Other banned items include flammable or explosive products, such as fuel and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your main priority is to feel as comfortable as you can. Choose 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. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to improve your circulation.
How to get through airport security fast when flying to Rainier?
The trick is to be well prepared before you arrive at the airport security gate. That way, you'll be hopping onto that plane to Rainier in next to no time. Follow these tips and get your vacation off to a flying start:
  • Be sure to have your passport and travel documents someplace easily accessible. They're the first items you'll be asked to present to airport security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll have to unplug from the digital world. Your phone, tablet and any other electronic gadgets also need to be sent through the scanner.
  • Want to bring along your favourite cologne or perfume? 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-lock bag, it's OK to bring with you in your carry-on.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Big boots and other heavy-style shoes are usually subjected to extra screening.
  • Pocket knives and other sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked baggage.
