Do you have any tips for my flight to Kostenets?
If you're not prepared, travelling can be a real challenge. But there's no need to worry. Follow these handy tips and enjoy a pain-free start to your time in Kostenets. What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, official ID, credit cards and vital medications. Next, you'll need some in-flight entertainment to while away the time. A thrilling book and a phone crammed with your favourite shows are always good options. If you plan to catch a few z's, a quality neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a toothbrush and some facial wipes to ensure you hop off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also restricted.

What to wear on a flight:

  • Your top priority is to be as comfortable as you can. Go for shoes that are easy to pull on and off, dress in loose, natural fibers and remember to take a jacket in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Kostenets?
The answer is — be prepared. We've compiled some helpful hints for a fuss-free trip through airport security. Watch out Kostenets, here you come:

  • First things first. Your travel documents and passport will need to be inspected by airport security. Keep them at hand so you don't have to dig around for them.
  • Next up, both you and your carry-on bag will be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings like your belt, jacket and headphones will be required to go through the machine.
  • For just a few moments, you'll need to unplug from technology. Your phone, tablet and any other electronic devices will also need to be sent through the scanner.
  • Travelling with a new hand cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're permitted to bring it with you in your carry-on luggage.
  • There's a chance you'll be asked to take your shoes off for scanning, so wearing slip-on sneakers is always a smart idea.
  • Airlines will not allow any sharp or pointed objects in your hand luggage. If you must bring these kinds of items, put them in your checked luggage.
