Cheap Flights to Sun Valley , CA from CA $125

We've got the lowdown on how to make your flight an enjoyable experience. Follow our insider tips and you'll be cruising through airport security and having a ball in Sun Valley in next to no time. What to pack in your hand luggage:

• Firstly, and most importantly, pack in your passport, travel docs, cash and medications. Next, you'll want some in-flight entertainment to while away the time. A juicy book and a laptop filled with your favourite shows are always good options. If you intend to take a quick snooze, a comfy neck pillow and some earplugs will also be useful. Finally, make room for a few toiletry items so you'll hop off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a sharp object hiding in the bottom of your hand luggage. Other prohibited items include explosive or flammable products, such as aerosol cans and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for temperature changes in the cabin by donning layers, and opt for flat, closed-toe footwear like sneakers.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.

The simple answer is — be prepared. We've pulled together some top tips for a stress-free trip through security. Watch out Sun Valley, here you come:

• Be sure to keep your travel documents and ID easily accessible. They're the first items you'll be asked to present to security.
• Next up, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that might set the alarms off. Personal belongings like your belt, jacket and earphones need to go through the machine.
• Your electronic devices like laptops and phones will also need to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
• Any gels or liquids, such as perfume or toothpaste, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a sensible footwear choice as you're less likely to have to remove them when going through security. Boots and heavier-style shoes are often subjected to additional screening.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed in the cabin.
