Frequently asked questions

How to book the cheapest flight to Sirena?
If you'd like to save some cash on your Sirena holiday, then listen up! As every seasoned jet-setter will tell you, don't book at the very last minute. Prices are usually more expensive close to the departure date. Another fantastic way to land the most competitive fare is to compare all options. If your destination has multiple airports, be sure to look into the cost of flying into a smaller terminal. And finally, remember that the early bird catches the worm. Know what a typical airfare costs and be ready to buy your ticket as soon as you spot a bargain. The sweetest deals don't last long.
Do you have any tips for my flight to Sirena?
Depending on where you're coming from, your journey to Sirena could be no sweat at all or it could go on forever. We've put together some useful hints that will help you start your next great escape on a positive note. What to pack in your hand luggage:

  • It's simple — first, pack in your passport, travel docs, credit cards and vital medications. Next, you'll want some extra in-flight entertainment to while away the time. A juicy novel and a phone crammed with your favourite shows are some wonderful options. If you intend to catch forty winks, a neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some deodorant to ensure you step off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) hiding in the bottom of your hand luggage. Other prohibited items include flammable or explosive products, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your top priority is to be as comfortable as you can. Pick shoes that are easy to slip on and off, dress in loose, breathable clothing and don't forget to bring a jacket in case you get chilly in the cabin.
  • You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lessen your risk on board, drink lots of water, consider wearing compression tights or socks and move your legs and feet often.

How to get through airport security fast when flying to Sirena?
Being prepared before your flight will help make your getaway to Sirena easy and painless. Read through our handy tips and tricks for a swift journey through security:

  • Security personnel first need to check that you have a valid ID and matching boarding pass before you can proceed any further. Have them ready to show.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronic gadgets, including your phone and laptop, will also need to be scanned.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and heavier-style shoes are often subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed on board and will be confiscated.
