Do you have any tips for my flight to Welwyn?
We've pulled together all the info you need to make your journey as stress-free as possible. Follow our insider tips and you'll be breezing through the airport and having a ball in Welwyn in no time. What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you carry the right stuff. First of all you'll need basic toiletry items, such as a toothbrush and lip balm, a spare pair of socks and a good read. Next, find a spot in your bag for your mobile phone, a charger, medications and perhaps a neck pillow too. Lastly, remember to take your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a knife or scissors) hiding in one of the compartments of your carry-on luggage. Other prohibited items include explosive or flammable goods, such as fuel and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Layer up with comfortable clothing and go for shoes that are flat, enclosed and easy to remove.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lessen your risk on board, stay hydrated, consider wearing compression socks or tights and keep your legs and feet moving.

How to get through airport security fast when flying to Welwyn?
The secret is to be organised before you get to security. That way, you'll be hopping onto that plane to Welwyn in next to no time. Follow these helpful tips and get your holiday off to a fantastic start:

  • Have your ID and boarding pass easily accessible. They'll be the first things you'll be asked to present to airport security.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Remember to remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other heavy-style shoes are often subjected to additional screening.
  • Sharp or pointed items can't be taken on board. They'll be confiscated at security, so put them in your checked baggage.
