Do you have any tips for my flight to Union Gap?
If you're not prepared, air travel can be testing. But there's no need to panic. Follow these handy hints and enjoy a hassle-free start to your holiday in Union Gap. What to pack in your hand luggage:

  • First, pack your passport, travel docs, credit cards and vital medications. Next, you'll need some extra in-flight entertainment to while away the time. A juicy novel and a tablet crammed with your favourite movies are good options. If you hope to catch more than just forty winks, a neck pillow and some earplugs will also come in handy. Finally, squeeze in a few toiletry items so you'll touchdown 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 rule to follow is avoid carrying anything flammable, sharp or explosive. This includes tools, metal cutlery, spray paint and flares. Sporting equipment like ski poles, and items that could injure passengers, such as guns and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • Your top priority is to be as comfortable as you can. Pick easy-to-remove footwear, dress in loose, breathable clothing and don't forget to take a pullover in case it gets cold in the cabin.
  • You've probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lessen your risk on board, drink plenty of water, consider wearing compression tights or socks and move your legs and feet often.

How to get through airport security fast when flying to Union Gap?
The trick is to be prepared before you reach the airport security gate. That way, you'll be hopping onto that plane to Union Gap in no time at all. Follow these tips and get your holiday off to a spectacular start:

  • First things first. Your boarding pass and travel ID will need to be inspected by airport security. Keep them at hand so you don't have to dig around for them.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as heavy coats or jackets. 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. No need to worry though, you'll be back online in no time.
  • Remove all gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other bulky shoes are often subjected to additional screening.
  • Sharp or pointed items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked baggage.
