Do you have any tips for my flight to Rancho Cucamonga?
Depending on where you're coming from, your flight to Rancho Cucamonga could be simple and straightforward or it could go on forever. We've put together some handy travel tips that will help you start your next great escape on a positive note. What to pack in your hand luggage:
  • Air travel can be a cruisy experience if you've got all the right things. First things first, you'll need basic toiletries, such as toothpaste, a toothbrush and some deodorant, a spare set of clothes and a good book. Secondly, make room in your bag for your phone, tablet and chargers, any vital medications and maybe a comfy neck pillow too. Last, but definitely not least, don't forget to take your passport, travel docs and some money.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of shampoo and hair gel in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, chemicals agents and matches, are also prohibited.
What to wear on a flight:
  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by donning layers, and pick flat, easy-to-remove shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clotting due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to Rancho Cucamonga?
Being prepared before you arrive at the airport will make your getaway to Rancho Cucamonga a piece of cake. Below are some useful tips for a speedy journey past security:
  • Be sure to keep your boarding pass and ID handy. They're the first things you'll be asked for by security.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Personal belongings such as your belt, jacket and headphones will be required to go through the machine.
  • All your electronics, including your phone and laptop, will also need to be separately scanned.
  • Any liquids or gels, such as perfume or toothpaste, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Avoid taking prohibited items in 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.
