Do you have any tips for my flight to Watertown?
Wherever you're coming from, flying can be an enjoyable experience if you've prepared well. We've compiled a list of handy tips that will get your Watertown holiday started on the right note. What to pack in your hand luggage:

  • The trick to having a stress-free flight experience is to pack in advance. So, let's start with the essentials: passport, official ID, bank cards and any vital medications. Next, take on board items that'll help keep you entertained, like some electronic gadgets or a thrilling novel. It's also a wise idea to pack your chargers, a comfy neck pillow and a pair of earplugs. And of course, don't forget to toss in toiletry items like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, knives, fuels and bleaching agents. Sporting equipment like ice skates, and objects that could harm other people, such as pepper spray and guns, won't be allowed on board either.

What to wear on a flight:

  • Your top priority is to feel as comfortable as possible. Opt for a pair of flat, closed-toe shoes, dress in loose, breathable clothing and remember to bring a pullover in case you get cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged 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.

How to get through airport security fast when flying to Watertown?
It's easy — be prepared. We've compiled some tips and tricks for an easy trip through security. Look out Watertown, here you come:

  • Airport security personnel first need to check that you have a valid ID and matching boarding pass before you're allowed to proceed any further. Have them ready for inspection.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. 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 your electronics, including your phone and tablet, are also required to be scanned separately.
  • Don't forget to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a clever idea.
  • Sharp items such as knives and scissors can't be taken on board. They'll be confiscated at security, so pack them in your checked suitcase.
