Do you have any tips for my flight to Custer?
We've rounded up all the info you need to make your flight as stress-free as possible. Follow our tips and you'll be breezing through the airport and discovering Custer in next to no time. What to pack in your hand luggage:

  • The trick to having a stress-free travel experience is to pack ahead. Start with the essentials: passport, travel documents, bank cards and vital medications. Next, take on board items that'll help keep you entertained, like some electronic gadgets or a thrilling novel. It's also smart to pack your chargers, a comfy neck pillow and a pair of earphones. And of course, don't forget to squeeze in toiletries like a toothbrush, lip balm and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) won't be allowed on. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and strong acids, are also not allowed.

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and opt for shoes that are flat, enclosed and easy to pull on and off.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. Lower your 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 Custer?
The secret is to be well prepared before you get to the security gate. That way, you'll be stepping onto that plane to Custer in no time flat. Follow these tips and get your trip off to a spectacular start:

  • Security personnel first need to verify that you have a valid ID and matching boarding pass before you're allowed to proceed any further. Keep them within easy reach.
  • Time to strip down. Well kind of. Your belt, coat, keys and other contents of your pockets, like your earphones, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn.
  • All your electronic gadgets, including your phone and laptop, will also need to be separately scanned.
  • Can't travel without your favorite cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on luggage.
  • 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 usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won't be allowed on board.
