Do you have any tips for my flight to San Ysidro?
We've got the lowdown on how to make your journey a stress-free experience. Follow our tips and you'll be cruising through the airport and seeing the best of San Ysidro in no time. What to pack in your hand luggage:

  • It's easy — first, pack in your passport, important documents, cash and medications. Next, you'll need some entertainment to while away the hours. A thrilling book and a tablet crammed with your favourite shows are good options. If you hope to catch more than just forty winks, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave space for a toothbrush and some facial wipes to ensure you step off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a pocket knife) hiding in the bottom of your carry-on luggage. Other restricted items include explosive or flammable goods, such as aerosol cans and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by donning layers, and opt for closed-toe, flat shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clots forming due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to San Ysidro?
As savvy travellers know, the secret is to be well prepared before you reach airport security. That way, you'll be stepping onto that plane to San Ysidro before you know it. Follow these tips and get your trip off to a terrific start:

  • Have your ID and boarding pass at hand. They'll be the first things you'll be asked to show at security.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items such as your jacket, belt and headphones need to go through the machine.
  • Your electronic devices like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online soon enough.
  • Any gels or liquids, such as shampoo or hairspray, that you want to take 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), clear zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to have to remove them when going through security. Big boots and other heavy shoes are often subjected to extra screening.
  • Avoid taking prohibited items in 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.
