Do you have any tips for my flight to Boston Harbour?
Depending on where you're coming from, your journey to Boston Harbour could be as easy as pie or it could go on forever. Below are some useful hints that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

  • It's easy — first, pack in your passport, important documents, bank cards and medications. Next, you'll need some in-flight entertainment to while away the time. A thrilling novel and a laptop crammed with your favourite shows are good options. If you hope to take a quick snooze, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some facial wipes to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes screwdrivers, drills, spray paint and flares. Sporting equipment like hockey sticks, and items that could harm passengers, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

  • Your main priority is to feel as comfortable as you can. Opt for a pair of flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to take a sweater in case you get cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Boston Harbour?
The secret is to be well prepared before you arrive at the security gate. That way, you'll be stepping onto that plane to Boston Harbour before you know it. Follow these tips and get your trip off to a terrific start:

  • Security personnel first need to establish that you have a valid ID and travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • The X-ray machine is up next. Remove anything metal on you that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All your electronics, including your laptop and phone, are also required to be scanned.
  • Any gels or liquids, such as shampoo or hairspray, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several minutes. Boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won't be allowed on board and will be confiscated.
