Do you have any tips for my flight to Fontana?
Wherever you're jetting in from, flying can be a pleasurable experience if you're prepared. Check out these handy travel tips that will get your Fontana holiday started on the right note. What to pack in your hand luggage:

  • The secret to having an amazing travel experience is to pack in advance. First up, the essentials: passport, travel docs, cash and any vital medications. Next, bring on board items that'll help keep you entertained, like some electronic gadgets or a thrilling novel. It's also smart to bring your chargers, a quality neck pillow and a pair of earphones. And of course, be sure to toss in toiletry items like a toothbrush, lip balm and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like a Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, bleaching agents and fuels, are also not allowed.

What to wear on a flight:

  • Your main aim is to be as comfortable as you can. Opt for easy-to-remove footwear, dress in loose, natural-fibre clothing and remember to bring a sweater in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Fontana?
It's all about being organised. We've compiled some tips and tricks for a fuss-free trip through security. Look out Fontana, here you come:

  • First things first. Your travel documents and passport will need to be shown to security personnel. Keep them at hand so you don't hold up the queue.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might set the alarms off. Items like your jacket, belt and earphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronic gadgets will need to be sent through the scanner.
  • Don't forget to remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Sharp items like knives are not allowed on board. They'll be seized at security, so put them in your checked bags.
