Do you have any tips for my flight to Houston?
Wherever you're coming from, flying can be a pleasurable experience if you're well prepared. Take a peek at these handy tips and tricks that will help get your Houston escape started on the right note. What to pack in your hand luggage:

  • First things first, pack your passport, travel documents, bank cards and medications. Next, you'll want some in-flight entertainment to while away the time. A juicy book and a phone crammed with your favourite shows are some great options. If you hope to take a quick snooze, a quality neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, make room for a toothbrush and some cleansing wipes so you'll touchdown looking 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 hiding in your hand luggage. Other prohibited items include flammable or explosive goods, such as bleach 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:

  • The aisles of an aircraft are no place for a fashion parade. Layer your clothing and opt for shoes that are roomy, flat and easy to slip on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your legs and feet moving.

How to get through airport security fast when flying to Houston?
As savvy travellers know, the secret is to be prepared before you arrive at the security gate. That way, you'll be hopping onto that plane to Houston in a flash. Follow these tips and get your holiday off to a fantastic start:

  • Airport security personnel first need to check that you have a valid passport and matching boarding pass before anything else. Keep them within easy reach.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All electronic devices, including your phone and laptop, will also need to be scanned.
  • Any gels or liquids, such as shampoo or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to have to remove them when passing through security. Boots and heavier-style shoes are usually subjected to extra screening.
  • Sharp items such as knives and scissors are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage.
