Do you have any tips for my flight to Sumas?
Depending on where you're coming from, your flight to Sumas could be as easy as pie or it could go on forever. Here are some handy tips that will help you start your next big adventure on a positive note. What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, travel documents, credit cards and vital medications. Next, you'll need some extra in-flight entertainment to while away the hours. A juicy book and a tablet filled with your favourite movies are some wonderful options. If you hope to catch forty winks, a quality neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a sharp object lurking in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive goods, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane are no place for a fashion parade. Dress in comfortable layers and pick shoes that are flat and easy to slip on and off.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Sumas?
The secret is to be prepared before you arrive at airport security. That way, you'll be boarding that plane to Sumas in next to no time. Follow these tips and get your trip off to a fantastic start:

  • First things first. Your travel ID and boarding pass will need to be shown to airport security. Keep them handy to avoid fumbling around for them.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll have to unplug from technology. Your laptop, phone and any other electronic gadgets also need to be sent through the scanner.
  • Want to bring along your favourite perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's OK to bring with you in your carry-on bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy shoes are usually subjected to extra screening.
  • Airlines won't allow any pocket knives or other sharp items in your carry-on baggage. If you must bring these kinds of items, pack them in your checked baggage.
