How to survive the flight to Sejny?
If you’re poorly prepared, travelling can be overwhelming. But there’s no need to worry. Follow these handy tips for a stress-free start to your holiday in Sejny.What to pack in your hand luggage:

  • Travelling on a plane can be easy if you pack the right things. First things first, you’ll need toiletry items, such as a toothbrush and hairbrush, a clean pair of socks and a good book. Secondly, make room in your bag for your electronic gadgets, chargers, your important medications and maybe a comfy neck pillow as well. Lastly, be sure to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Check carefully that you don’t have sharp objects (like a pocket knife) hiding in one of the zippers of your carry-on luggage. Other restricted items include flammable or explosive substances, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your number one priority is to be as comfortable as you can. Layer up with loose, natural-fibre clothing and take a pullover in case it gets cold in the cabin. Always opt for well-fitting, flat shoes as your feet may swell a little during the flight. Leave the high heels and heavy boots in your checked baggage.
  • Unfortunately, one risk of flying long distances is developing DVT (deep vein thrombosis), a blood clotting condition caused by prolonged periods of inactivity. To prevent this, make the most of every opportunity to wander around the cabin. Compression tights and socks are another great idea to help reduce this risk.

How to get through airport security fast when flying to Sejny?
A little pre-planning before your flight will make your getaway to Sejny a pleasure. Check out our handy tips for a speedy journey through security:

  • Your ID and travel documents will need to be presented to airport security. Keep them within easy reach to avoid fumbling around for them.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as your coat or jacket. They’ll all need to go on the X-ray conveyor belt.
  • Your electronic devices like laptops and phones will also have to go on a tray to be scanned. Don’t worry, you’ll be back online in no time.
  • Remember to remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several valuable minutes. Boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Sharp items are prohibited in the cabin. They’ll be confiscated at security, so pack them safely away in your checked luggage.
