Do you have any tips for my flight to South Boston?
Depending on where you're coming from, your flight to South Boston could be simple and straightforward or it could drag on forever. Here are some handy hints that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

  • Firstly, and most importantly, put in your passport, travel documents, cash and vital medications. Next, you'll want some extra in-flight entertainment to help pass the time. A juicy novel and a tablet crammed with your favourite movies are good options. If you plan to take a short snooze, a quality neck pillow and some earplugs will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you arrive looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a sharp object hiding in your carry-on luggage. Other restricted items include flammable or explosive substances, such as fuel and fireworks, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane are no place for a fashion parade. Layer up with comfortable clothing and pick shoes that are roomy, flat and easy to slip on and off.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to South Boston?
The simple answer is — be prepared. We've put together some top tips for a stress-free trip through security. Look out South Boston, here you come:

  • Be sure to keep your boarding pass and ID close by. They'll be the first things you'll be asked for by airport security.
  • The X-ray machine comes next. Remove anything metal on you that is likely to beep. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • All electronic devices, including your tablet and phone, must also be scanned.
  • Travelling with your favourite perfume? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can bring it with you in your carry-on baggage.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when passing through security. Big boots and other bulky shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won't be allowed on board.
