Do you have any tips for my flight to Slough?
Wherever you're coming from, flying can be a pleasant experience if you prepare well enough. We've put together a list of handy hints that will help get your Slough escape started on the right foot. What to pack in your hand luggage:

  • The trick to having an awesome flight experience is to pack in advance. First up, the essentials: passport, official ID, bank cards and daily medications. Next, bring on board items that'll help keep you entertained, like your laptop or a few magazines. It's also wise to pack your chargers, a quality neck pillow and a pair of earphones. Finally, be sure to toss in toiletry items like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your beloved pocket knife, and dangerous goods which are explosive or flammable, such as flares, bleaching agents and fireworks, are also banned.

What to wear on a flight:

  • Comfort should be your number one priority when deciding what to wear on your flight. Loose clothing is a smart choice, as are flat, slightly roomy shoes.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression tights or socks and move your legs and feet often.

How to get through airport security fast when flying to Slough?
Being organized before you arrive at the airport will make your trip to Slough a pleasure. We've rounded up some handy tips for a stress-free journey through security:

  • Your travel ID and boarding pass will need to be inspected by security personnel. Keep them at hand to avoid fumbling around for them.
  • After that, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that might set the alarms off. Personal belongings such as your jacket, belt and earphones need to go through the machine.
  • All your electronic devices, including your laptop and phone, must also be separately scanned.
  • Any liquids or gels, such as lip balm or cologne, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be asked to remove them when going through security. Boots and other bulky shoes are usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board.
