Do you have any tips for my flight to Petersburg?
We've got the lowdown on how to make your journey as enjoyable as possible. Follow our tips and you'll be cruising through the airport and seeing the best of Petersburg in no time flat. What to pack in your hand luggage:

  • Travelling on a plane can be a stress-free experience if you carry the right stuff. Firstly, you'll want some basic toiletry items, such as a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Next, leave space in your carry-on bag for your phone and charger, medications and maybe a proper neck pillow too. Last, but definitely not least, be sure to bring your passport, travel docs and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, spray paint and flares. Sporting equipment like baseball bats, and objects that could injure passengers, such as guns and swords, can't come on board with you either.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Layer your clothing and go for shoes that are flat, roomy and easy to slip on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To minimize your risk on board, drink lots of water, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Petersburg?
As savvy travellers know, the secret is to be prepared before you get to security. That way, you'll be stepping onto that plane to Petersburg in a flash. Follow these tips and get your trip off to a spectacular start:

  • First things first. Your passport and travel documents will need to be presented to airport security. Keep them handy to avoid fumbling around for them.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Personal belongings like your belt, coat and earphones will be required to go through the machine.
  • For just a few minutes, you'll have to unplug from the digital world. Your tablet, phone and any other electronic devices also need to be sent through the scanner.
  • Travelling with a new hand and nail cream? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on bag.
  • It's also likely that you'll need to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed on board.
