Do you have any tips for my flight to Chesterfield?
We've got the lowdown on how to make your flight a pleasant experience. Follow our tips and you'll be zooming through the airport and seeing the best of Chesterfield in no time flat. What to pack in your hand luggage:

  • It's easy --- first, pack in your passport, official ID, credit cards and vital medications. Next, you'll need some entertainment to help pass the time. A thrilling book and a tablet filled with your favourite movies are always good options. If you hope to take a quick nap, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some cleansing wipes to ensure you arrive looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes screwdrivers, blades, spray paint and fireworks. Sports equipment like ski poles, and items that could harm other people, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • Comfort should be your main concern when choosing what to wear during your flight. Loose clothing is a smart choice, as are flat, slip-on shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Chesterfield?
Being prepared before your flight can make your getaway to Chesterfield a pleasure. We've rounded up some top tips for a stress-free journey past security:

  • Your travel ID and boarding pass will need to be inspected by airport security personnel. Have them easily accessible so you don't hold up the queue.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. 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.
  • All your electronic devices, including your laptop and phone, will also need to be separately scanned.
  • Travelling with a new perfume or cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on luggage.
  • The right choice of footwear can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Sharp or pointed items are not allowed on board. They'll be seized at security, so pack them in your checked bags.
