Do you have any tips for my flight to Union Pier?
We've got the lowdown on how to make your flight as pain-free as possible. Follow our tips and you'll be speeding through the airport and enjoying Union Pier before you know it. What to pack in your hand luggage:
  • The trick to having a great flight experience is to be prepared. Start with the essentials: passport, official ID, bank cards and medications. Next, bring items that'll help keep you entertained, like some electronic gadgets or a magazine. It's also wise to pack your chargers, a comfy neck pillow and a pair of headphones. And of course, don't forget to squeeze in toiletry items like a toothbrush, deodorant and a clean set of clothes.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have sharp or pointed objects hiding in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive goods, like aerosols and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your main concern when deciding what to wear during your flight. Loose clothing is a sensible option, as are flat, slip-on shoes.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lower your risk on board, drink lots of water, consider wearing compression socks and keep your feet and legs moving.
How to get through airport security fast when flying to Union Pier?
As seasoned travellers know, the secret is to be well prepared before you get to airport security. That way, you'll be stepping onto that plane to Union Pier before you know it. Follow these helpful tips and get your trip off to a great start:
  • Airport security personnel first need to see that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Personal belongings like your belt, jacket and headphones need to go through the machine.
  • Your electronic devices like phones and laptops will also need to go on a tray to be scanned. Don't worry though, you'll be back online before you know it.
  • Remember to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner 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-close bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board and will be confiscated.
