Do you have any tips for my flight to St Mary?
- First and foremost, pack your passport, travel documents, credit cards and medications. Next, you'll need some extra in-flight entertainment to while away the time. A thrilling novel and a phone crammed with your favourite movies are some fantastic options. If you plan to catch more than just forty winks, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes so you'll arrive feeling fresh and raring to go.
- Check carefully that you don't have a Swiss Army knife lurking in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive goods, such as fuel and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).
- Your main aim is to be as comfortable as you can. Opt for shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and don't forget to take a sweater in case you get chilly in the cabin.
- Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to improve your circulation.
How to get through airport security fast when flying to St Mary?
- Be sure to have your passport and travel documents within easy reach. They're the first items you'll be asked to show at security.
- Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
- For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets will need to go through the scanner.
- Travelling with your favourite perfume or cologne? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you in your carry-on baggage.
- There's a chance you'll be required to take your shoes off for scanning, so wearing slip-on sneakers is always a good idea.
- Pocket knives and other sharp items can't be taken on board. They'll be seized at security, so put them in your checked suitcase.
