How to survive the flight to Rancho Cucamonga?
No matter where you're coming from, flying can be an enjoyable experience if you've prepared well. We've made a list of essential travel tips that will get your Rancho Cucamonga holiday started on the right note.What to pack in your hand luggage:

  • The trick to having a great flight experience is to be prepared. First up, the essentials: passport, travel docs, credit cards and medications. Next, take on board items that'll help while away those hours, like some electronic devices or a good book. It's also smart to bring your chargers, a neck pillow and a pair of headphones. Finally, be sure to chuck in toiletry items like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp or pointed objects lurking in the bottom of your carry-on luggage. Other restricted items include explosive or flammable products, such as fuel and fireworks, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Comfort should be your highest priority when deciding what to wear on your flight. Consider your footwear carefully too, as swollen feet and ankles are quite common. Slightly roomy, flat shoes work well.
  • The result of sustained periods of immobility, DVT (deep vein thrombosis) is a serious condition that can affect some passengers during long flights. The great news is there are proven ways to significantly reduce your risk of developing it. Drink plenty of water, walk around the cabin as often as you can and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to Rancho Cucamonga?
Being organised before you arrive at the airport will make your trip to Rancho Cucamonga easy and painless. We've compiled some handy tips and tricks for a swift journey through security:

  • Airport security personnel first need to make sure that you have a valid passport and travel documents before you're allowed to proceed any further. Have them close by, ready for inspection.
  • Your jacket, belt, keys and other items in your pocket, like coins, will be required to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • Your electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each item 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-lock bag.
  • There's a chance you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a smart idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed in the cabin.
