Do you have any tips for my flight to Petersburg?
We've rounded up all the info you need to make your flight an enjoyable experience. Follow our tips and tricks and you'll be breezing through the airport and having a ball in Petersburg before you know it. What to pack in your hand luggage:

  • It's easy — first, put in your passport, official ID, bank cards and vital medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling novel and a laptop crammed with your favourite movies are always good options. If you intend to catch a few z's, a neck pillow and some earplugs will also come in handy. Finally, leave space for a toothbrush and some deodorant so you'll hop off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, drills, fuels and bleaching agents. Sports equipment like ice skates, and items that could harm other people, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Dress in comfortable layers and opt for shoes that are roomy, flat and easy to take on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lower your risk on board, drink plenty of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Petersburg?
Being prepared before you get to the airport can make your getaway to Petersburg quick and painless. We've rounded up some handy tips for a speedy journey past security:

  • Keep your travel documents and ID at hand. They're the first items you'll be asked to show at airport security.
  • Time to strip down. Well sort of. Your coat, belt, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • Electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Can't travel without your favourite hand and nail cream? Not a problem. As long as the volume is no larger 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 baggage.
  • Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Sharp items are not allowed on board. They'll be seized at security, so pack them in your checked bags.
