Tips on getting the best Seattle airfare

If you're interested in getting the cheapest tickets to Seattle, consider going during the low season months of November through April. Although it does rain throughout the year, the majority of the rain occurs during the fall and winter. Due to the rain, you'll find great prices on hotels and discounts on many attractions. High season is from May to October; you'll pay more for tickets, but you'll get to attend some of the numerous festivals going on during those months. If you want to save money on your tickets, try booking them as early as possible; tickets tend to get more expensive as the departure date nears. However, another tactic is to get tickets at the very last minute; if an airport hasn't been able to sell all the tickets on a particular flight, oftentimes, it will release those leftover tickets at a shockingly low price, but you'll have to move fast in order to snatch those tickets up in time.

How to survive the flight to Seattle?
If you’re not prepared, traveling can be a real challenge. But there’s no need to worry. Follow these handy tips and enjoy a comfortable start to your time in Seattle.What to pack in your hand luggage:

  • The secret to having a great flight experience is to be prepared. So, let’s start with the basics: passport, travel documents, cash and any vital medications. Next, take on board items that’ll help keep you entertained, like your laptop or a good book. It’s also smart to pack your chargers, a quality neck pillow and a pair of earphones. Finally, be sure to squeeze in toiletries like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general guide to follow is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, aerosol cans and flares. Sports equipment like hockey sticks, and objects that could injure passengers, such as swords and batons, won’t be allowed on board either.

What to wear on a flight:

  • Comfort should be your prime concern when choosing what to wear on board. Consider your choice of footwear carefully too, as swollen ankles and feet are a common side effect of flying. Flat, slightly roomy shoes work well.
  • Unfortunately, one risk of long-haul flights is developing DVT (deep vein thrombosis), a blood clotting condition caused by extended periods of inactivity. To avoid this, make the most of every opportunity to walk around and give your legs a stretch. Compression socks and tights are another great idea to help minimize this risk.

How to get through airport security fast when flying to Seattle?
The secret is to be prepared before you get to security. That way, you’ll be hopping onto that plane to Seattle in no time flat. Follow these tips and get your trip off to a flying start:

  • Airport security personnel first need to determine that you have a valid passport and matching travel documents before you’re allowed to proceed any further. Keep them close by.
  • The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They’ll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you’ll have to unplug from technology. Your laptop, phone and any other electronic devices also need to be sent through the scanner.
  • Traveling with your favorite hand cream? As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a zip-close bag, you can bring it with you in your carry-on baggage.
  • Slip-on shoes are a good footwear choice as you’re less likely to have to remove them when going through security. Big boots and heavier-style shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp or pointed objects in your hand luggage. If you need to bring these kinds of items, pack them safely in your checked baggage.
