Do you have any tips for my flight to Seneca?
We've pulled together all the info you need to make your journey a stress-free experience. Follow our insider tips and you'll be zooming through airport security and seeing the best of Seneca in no time. What to pack in your hand luggage:

  • A plane ride can be easy if you bring the right stuff. First things first, you'll need basic toiletries, such as toothpaste, a toothbrush and some deodorant, a spare set of clothes and something to read. Secondly, make room in your hand luggage for your electronic devices, chargers, your medications and maybe a cozy neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes tools, metal cutlery, fuel and fireworks. Sporting equipment like baseball bats, and objects that could harm passengers, such as swords and guns, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your main concern when deciding what to wear on your flight. Loose, breathable clothing is a sensible choice, as are enclosed shoes like sneakers.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help improve your circulation.

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

  • Your travel documents and ID will need to be presented to airport security. Keep them at hand so you don't have to dig around for them.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. 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.
  • Your electronic devices like laptops and phones will also need to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
  • Remove all gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when passing through security. Boots and other heavy shoes are usually subjected to extra screening.
  • Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked baggage.
