Do you have any tips for my flight to San Diego de la Unión?
Depending on where you're coming from, your journey to San Diego de la Unión could be completely painless or it could go on forever. Here are some handy hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • First of all, pack your passport, official ID, bank cards and medications. Next, you'll want some in-flight entertainment to while away the time. A thrilling novel and a laptop filled with your favourite shows are always good options. If you hope to take a short snooze, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some deodorant to ensure you arrive at your destination feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects lurking 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 with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your priority when deciding what to wear on your flight. Loose clothing is a sensible option, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clots forming 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 Diego de la Unión?
The trick is to be organised before you reach the airport security gate. That way, you'll be hopping onto that plane to San Diego de la Unión in no time flat. Follow these helpful tips and get your holiday off to a spectacular start:

  • Your travel documents and passport will need to be inspected by airport security personnel. Have them close by to avoid fumbling around for them.
  • The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you'll need to unplug from the digital world. Your laptop, phone and any other electronics also need to go through the scanner.
  • Remove all liquids and gels from your carry-on luggage. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Boots and heavier-style shoes are often subjected to extra screening.
  • Sharp items such as knives and scissors are not allowed in the cabin. They'll be seized at security, so put them in your checked luggage.
