Depending on where you're coming from, your flight to San Ysidro could be a piece of cake or it could drag on forever. We've rounded up some useful travel tips that will help you start your next great adventure on a positive note.What to pack in your hand luggage:

• The secret to having an amazing travel experience is to be prepared. Start with the essentials: passport, official ID, credit cards and vital medications. Next, take on board items that'll help while away those hours, like your laptop or a good read. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of earphones. And of course, be sure to pop in toiletries like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between airlines, the general guide to follow is nothing flammable, sharp or explosive. This includes screwdrivers, knives, fuels and bleaching agents. Sporting equipment like golf clubs, and items that could injure passengers, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

• Comfort really should be your main priority when selecting what to wear on your flight. Consider your footwear choice with care too, as swollen ankles and feet are a common side effect of flying. Slightly roomy, flat shoes work well.
• The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. But the great news is there are numerous ways to significantly reduce the risk of developing it. Stay hydrated, wander around the cabin as often as possible and wear compression socks or tights.

The secret is to be prepared before you reach security. That way, you'll be hopping onto that plane to San Ysidro in the blink of an eye. Follow these tips and get your trip off to a fantastic start:

• Have your boarding pass and ID handy. They're the first items you'll be asked to present to airport security.
• The X-ray machine is up next. Remove anything on you that is likely to beep. 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 electronic devices, including your tablet and phone, must also be scanned separately.
• Any liquids or gels, such as perfume or hairspray, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), clear zip-lock bag.
• The right choice of footwear can save you a few precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes are usually not.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be seized at security, so put them in your checked suitcase.
