Do you have any tips for my flight to Sejny?

  • What you pack in your carry-on can make the difference between a comfortable flight, and a restless one. Start with the essentials, such as a valid ID (like your passport) and your travel documents. Once they’re safely packed, throw in any medications you might need. Next? It’s all about the comfort factor. A neck pillow, noise-canceling headphones and a book will help the time fly by while you’re soaring above the clouds.
  • It also pays to check with your airline regarding what you can’t bring on board your flight. Razor blades, pocket knives, swords and batons are among the prohibited items. Anything flammable, explosive or sharp is generally not allowed in your hand baggage. Don’t forget to pack any sports equipment like baseball bats or ski poles only in your checked luggage.

What to wear on a flight:

  • Whether traveling long or short-haul, layering up is key to a comfy flight. Wear loose, breathable fabrics that will keep you cool and pack a sweater for any in-flight temperature variations. Your feet will be happiest in a pair of closed-toe shoes or sneakers.
  • Consider wearing compression tights or socks to reduce the risk of deep vein thrombosis (DVT). This blood clotting condition can be caused by extended periods of sitting, especially on long journeys. Performing foot and leg stretches in your seat or wandering around the cabin are great ways to improve your circulation.

How can I get a cheap last-minute flight to Sejny?
Booking a cheap, last-minute flight to Sejny is as easy as having some flexibility with your travel plans. Keep your options open with your choice of airline, flight times and travel dates.
