How to survive the flight to Riverside?
If you're poorly prepared, air travel can be challenging. But don't hit the panic button just yet. Follow these tips and tricks for a comfortable start to your time in Riverside.What to pack in your hand luggage:

  • First of all, pack your passport, travel documents, bank cards and vital medications. Next, you'll need some extra in-flight entertainment to while away the time. A thrilling book and a laptop filled with your favorite movies are some terrific options. If you intend to take a short snooze, a quality neck pillow and some noise-canceling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes so you'll touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a pocket knife hiding in one of the zippers of your hand luggage. Other prohibited items include flammable or explosive substances, such as aerosol cans and fuel, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of your airplane are no place for a fashion parade. Layer up with comfortable clothing and bring a cardigan as it tends to get cool in the cabin on long-haul flights. Slightly roomy, flat shoes are also recommended.
  • The result of sustained periods of immobility, DVT (deep vein thrombosis) is a blood clot condition that can affect passengers during long flights. The great news is there are proven ways to lower your risk of developing it. Stay well hydrated, walk up and down the aisles wherever possible and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to Riverside?
The trick is to be prepared before you arrive at security. That way, you'll be hopping onto that plane to Riverside in next to no time. Follow these helpful tips and get your trip off to a flying start:

  • Your travel documents and ID will need to be inspected by airport security personnel. Keep them within easy reach to avoid fumbling around for them.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your phone and laptop, are also required to be separately scanned.
  • Don't forget to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray scanner 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 liter), clear zip-lock bag.
  • Choosing your footwear wisely can save you several minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked luggage. They won't be allowed in the cabin.
