Do you have any tips for my flight to Lock?
If you're poorly prepared, travelling can be tough. But there's no need to panic. Follow these helpful hints for a trouble-free start to your time in Lock. What to pack in your hand luggage:

  • A plane ride can be a comfortable experience if you've got all the right stuff. First things first, you'll need basic toiletry items, such as lip balm and hand cream, a spare set of clothes and something to read. Secondly, find a spot in your bag for your mobile phone, a charger, your important medications and perhaps a cosy neck pillow too. Lastly, and most importantly, don't forget to bring your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a pocket knife lurking in one of the zippers of your hand luggage. Other banned items include explosive or flammable products, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in temperature by wearing layers, and opt for flat, enclosed shoes like slip-ons.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To minimize your risk on board, drink plenty of water, consider wearing compression socks or tights and keep your legs and feet moving.

How to get through airport security fast when flying to Lock?
Being prepared before you arrive at the airport will help make your getaway to Lock a breeze. Below you'll find some useful tips for a swift journey past security:

  • Be sure to have your passport and travel documents within easy reach. They'll be the first things you'll be asked to present to airport security.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Items like your coat, belt and earphones need to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your phone, tablet and any other electronics must also go through the scanner.
  • Any gels or liquids, such as perfume or hairspray, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • It's also likely that you'll need to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a smart idea.
  • 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 and will be confiscated.
