We've rounded up all the info you need to make your flight a pleasant experience. Follow our tips and you'll be zooming through the airport and discovering Gretna in no time flat. What to pack in your hand luggage:

• The secret to having a hassle-free travel experience is to be prepared. First up, the essentials: passport, travel documents, bank cards and vital medications. Next, bring items that'll help keep you entertained, like some electronic devices or a magazine. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of headphones. Finally, be sure to pop in toiletries like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like box cutters, razor blades, spray paint and fireworks. Sporting equipment like golf clubs, and objects that could harm other people, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

• You'll want to go for comfort over style. Prepare for temperature changes in the cabin by layering up, and wear flat, slightly roomy footwear like slip-ons.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

Being prepared before you arrive at the airport will help make your trip to Gretna a piece of cake. Below you'll find some handy tips for a swift journey through security:

• Your passport and travel documents will need to be inspected by airport security. Keep them at hand so you don't hold up the line.
• Next up, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and headphones will be required to go through the machine.
• All electronic devices, including your phone and laptop, will also need to be scanned.
• Any liquids or gels, such as perfume or toothpaste, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
• Lightweight sneakers are a practical 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 additional screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed in the cabin.
