We've rounded up all the info you need to make your flight as stress-free as possible. Follow our tips and you'll be speeding through the airport and having a ball in Brentwood in next to no time. What to pack in your hand luggage:

  • First things first, put in your passport, important documents, wallet and vital medications. Next, you'll want some in-flight entertainment to while away the time. A thrilling novel and a tablet crammed with your favourite shows are some terrific options. If you intend to catch up on some sleep, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some deodorant to ensure you touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp objects (like a pocket knife) lurking in the bottom of your carry-on luggage. Other restricted items include flammable or explosive goods, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on board. Loose, breathable clothing is a smart choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clots forming due to inactivity and 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 Brentwood?
As savvy travellers know, the secret is to be well organized before you get to airport security. That way, you'll be hopping onto that plane to Brentwood in the blink of an eye. Follow these helpful tips and get your vacation off to a terrific start:

  • Be sure to have your travel documents and passport at hand. They'll be the first things you'll be asked to present to airport security.
  • After that, both you and your hand luggage will be X-rayed. To speed things up, take off anything that might set the alarms off. Personal belongings such as your belt, coat and earphones need to go through the machine.
  • All electronic gadgets, including your laptop and phone, must also be scanned.
  • Travelling with a new perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you in your carry-on baggage.
  • Slip-on shoes are a practical footwear choice as you're less likely to have to remove them when passing through security. Big boots and other heavy-style shoes are often subjected to extra screening.
  • Airlines won't allow any sharp or pointed objects in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
