Do you have any tips for my flight to San Ysidro?
We've rounded up all the info you need to make your journey a pleasant experience. Follow our tips and tricks and you'll be zooming through the airport and enjoying San Ysidro before you know it. What to pack in your hand luggage:

  • Flying can be a comfortable experience if you take the right gear. First of all you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a spare set of clothes and a good book. Secondly, find a spot in your carry-on bag for your phone and charger, any medications and perhaps a comfy neck pillow as well. Lastly, don't forget to bring your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes knives, scissors, aerosol cans and bleaching agents. Sporting equipment like baseball bats, and items that could harm other people, such as guns and swords, can't come on board with you either.

What to wear on a flight:

  • Your main priority is to feel as comfortable as you can. Pick a pair of slip-on shoes, dress in loose, natural-fibre clothing and remember to take a sweater in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to San Ysidro?
Being prepared before your flight will help make your getaway to San Ysidro quick and painless. We've compiled some useful tips for a swift journey through security:

  • Be sure to keep your ID and travel documents easily accessible. They're the first things you'll be asked to present to airport security.
  • The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All electronic devices, including your laptop and phone, are also required to be scanned separately.
  • Want to bring along your favourite hand cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can bring it with you on board.
  • It's also likely that you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a smart idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed on board and will be confiscated.
