How to survive the flight to Diamond Bar?
Depending on where you're coming from, your trip to Diamond Bar could be a piece of cake or it could drag on forever. We've put together some useful tips that will help you start your next big adventure on the right foot.What to pack in your hand luggage:
  • Air travel can be easy if you bring the right stuff. Firstly, you'll want a few basic toiletry items, such as a toothbrush and some deodorant, a clean pair of socks and a magazine or two. Next, make room in your hand luggage for your electronic devices, chargers, any daily medications and maybe a quality neck pillow as well. Lastly, and most importantly, remember to take your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:
  • Pack all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp or pointed objects, like a pocket knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and matches, are also banned.

What to wear on a flight:
  • The key to a comfortable flight can be as simple as your choice in clothes. Prepare yourself for varying temperatures by bringing layers. This will keep you nice and warm if the cabin begins to cool down. Shoes like sandals and heels are best left for other occasions. Instead, opt for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by reduced mobility or inactivity. There's plenty you can do to lower your risk. Wear compression socks or tights, drink lots of water and get your legs and feet moving. Walk around the cabin when possible or perform some stretches in your seat.

How to get through airport security fast when flying to Diamond Bar?
The answer is simple --- be prepared. We've pulled together some handy tips and tricks for an easy trip through airport security. Look out Diamond Bar, here you come:
  • First things first. Your travel ID and boarding pass will need to be presented to airport security personnel. Have them close by to avoid fumbling around for them.
  • Next up, both you and your hand luggage will be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings such as your belt, coat and headphones will be required to go through the machine.
  • Electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online soon enough.
  • Travelling with your favourite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, you can keep it with you in your carry-on baggage.
  • Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when going through security. Boots and other bulky shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
