Do you have any tips for my flight to St. Regis?
If you're poorly prepared, air travel can be a real challenge. But there's no need to panic. Follow these handy tips for a pain-free start to your getaway in St. Regis. What to pack in your hand luggage:

  • First and foremost, pack in your passport, travel documents, wallet and daily medications. Next, you'll need some entertainment to while away the time. A juicy novel and a phone crammed with your favourite shows are some wonderful options. If you hope to take a quick snooze, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a toothbrush and some deodorant so you'll arrive feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes box cutters, razor blades, aerosol cans and flares. Sports equipment like golf clubs, and items that could injure passengers, such as guns and swords, won't be allowed on board either.

What to wear on a flight:

  • Your aim here is to be as comfortable as you can. Choose shoes that are easy to slip on and off, dress in loose, breathable clothing and remember to take a sweater in case you get chilly in the cabin.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to St. Regis?
Being prepared before your flight will make your getaway to St. Regis quick and painless. We've rounded up some useful tips and tricks for a swift journey through security:

  • Keep your boarding pass and passport handy. They're the first things you'll be asked to show at security.
  • Next up, both you and your hand luggage will be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings such as your belt, coat and earphones will be required to go through the machine.
  • Electronic devices like phones and laptops will also have to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Travelling with a new perfume or cologne? No 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, it's OK to bring with you in your carry-on baggage.
  • There's a good chance you'll need to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a good idea.
  • 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 on board and will be confiscated.
