How to survive the flight to Adelanto?
We've got the lowdown on how to make your flight as stress-free as possible. Follow our insider tips and you'll be speeding through the airport and having a ball in Adelanto before you know it.What to pack in your hand luggage:
  • Flying can be a great experience if you pack the right things. Firstly, you'll want some basic toiletries, such as deodorant and a toothbrush, a fresh change of clothes and a good novel. Secondly, find a spot in your hand luggage for your electronic gadgets, chargers, any medications and maybe a blow-up neck pillow too. Lastly, remember to take your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:
  • Make sure you don't have a Swiss Army knife lurking in one of the zippers of your hand luggage. Other restricted items include explosive or flammable products, such as aerosol cans and fuel, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:
  • Comfort should be your main priority when choosing what to wear during your flight. Consider your choice of footwear carefully too, as swollen feet are a common side effect of flying. Shoes which are flat and slightly roomy work well.
  • Unfortunately, one risk of long-distance travel is developing DVT (deep vein thrombosis), a blood clotting condition caused by extended periods of inactivity. To prevent this, take every opportunity to wander around the cabin. Compression socks and tights are another easy way to help reduce this risk.

How to get through airport security fast when flying to Adelanto?
The trick is to be organised before you reach security. That way, you'll be hopping onto that plane to Adelanto in the blink of an eye. Follow these tips and get your holiday off to a great start:
  • Security personnel first need to establish that you have a valid passport and travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. 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 electronic devices, including your tablet and phone, must also be separately scanned.
  • Remove all liquids and gels from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Airlines won't allow any pocket knives or other sharp items in the cabin. If you need to bring these kinds of items, pack them in your checked baggage.
