Do you have any tips for my flight to St. Helens?
Wherever you're jetting in from, flying can be a pleasant experience if you're well organised. We've compiled a list of handy hints that will help get your St. Helens escape started on the right note. What to pack in your hand luggage:
  • First, pack your passport, travel docs, wallet and medications. Next, you'll want some entertainment to while away the hours. A thrilling novel and a phone filled with your favourite movies are some fantastic options. If you plan to take a short nap, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, find room for a toothbrush and some facial wipes so you'll hop off the plane feeling fresh and ready to go.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your pocket knife, and products which are explosive or flammable, such as aerosol cans, flares and gasoline, are also banned.
What to wear on a flight:
  • Comfort should be your priority when deciding what to wear on board. Loose, breathable clothing is a wise choice, as are roomy, closed-toe shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk 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 St. Helens?
As savvy travellers know, the secret is to be well organised before you get to airport security. That way, you'll be stepping onto that plane to St. Helens before you know it. Follow these tips and get your holiday off to a flying start:
  • Be sure to have your ID and boarding pass at hand. They're the first items you'll be asked to present to airport security.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Personal belongings like your coat, belt and headphones need to go through the machine.
  • Electronic devices like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online in no time.
  • Travelling with a new hand and nail cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're permitted to bring it with you in your carry-on.
  • Choosing your footwear wisely can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed in the cabin.
