### Do you have any tips for my flight to Oldcastle?

> - First of all, pack your passport, official ID, wallet and daily medications. Next, you'll want some in-flight entertainment to while away the time. A juicy book and a laptop crammed with your favourite shows are some wonderful options. If you hope to catch a few z's, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll step off the plane feeling fresh and raring to go.
> 
>   
> Do not pack the following items in your hand luggage:
> 
>   
> - Make sure you don't have a pocket knife lurking in one of the compartments of your carry-on luggage. Other banned items include flammable or explosive goods, such as aerosol cans and fuel, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).
> 
>   
> What to wear on a flight:
> 
>   
> - Go for comfort over style. Prepare for changes in cabin temperature by layering up, and wear slightly roomy, flat shoes like sneakers.
> - Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression tights or socks and do gentle foot and leg exercises in your seat.

### How to get through airport security fast when flying to Oldcastle?

> - Have your ID and boarding pass easily accessible. They'll be the first things you'll be asked to present to airport security.
> - Time to strip down. Well kind of. Your belt, coat, keys and other contents of your pockets, like coins, will need to go on a tray through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
> - Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
> - Remember to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
> - The right choice of footwear can save you several minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
> - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed on board.
