Do you have any tips for my flight to Watertown?
Depending on where you're coming from, your flight to Watertown could be as easy as pie or it could go on forever. We've compiled some useful tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

  • First of all, pack your passport, travel documents, cash and vital medications. Next, you'll need some entertainment to help pass the time. A juicy novel and a tablet filled with your favourite movies are some wonderful options. If you plan to take a quick snooze, a comfy neck pillow and some earplugs will also come in handy. Finally, leave some space for a few toiletry items so you'll arrive at your destination 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 zippers of your hand luggage. Other prohibited items include flammable or explosive substances, such as bleach and fuel, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on board. Loose, breathable clothing is a sensible option, as are flat, closed-toe shoes.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Reduce the risks by staying hydrated, keeping your feet and legs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Watertown?
The secret is to be prepared before you get to the airport security gate. That way, you'll be stepping onto that plane to Watertown in a flash. Follow these tips and get your vacation off to a terrific start:

  • Be sure to have your travel documents and passport within easy reach. They're the first items you'll be asked to show at security.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items like your belt, coat and headphones need to go through the machine.
  • For just a few minutes, you'll need to unplug from technology. Your laptop, phone and any other electronics must also go through the scanner.
  • Don't forget to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray 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.
  • There's a possibility that you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked luggage. They won't be allowed on board.
