Do you have any tips for my flight to Dumbarton?
We've pulled together all the info you need to make your flight as enjoyable as possible. Follow our tips and you'll be hightailing it through airport security and exploring Dumbarton in no time flat. What to pack in your hand luggage:
  • The secret to having a stress-free travel experience is to pack in advance. So, let's start with the basics: passport, official ID, credit cards and any vital medications. Next, bring items that'll help keep you busy, like some electronic gadgets or a magazine. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of headphones. Finally, don't forget to toss in toiletries like a toothbrush, facial wipes and a spare change of clothes.
Do not pack the following items in your hand luggage:
  • Make sure you don't have a Swiss Army knife lurking in your carry-on luggage. Other prohibited items include explosive or flammable goods, such as fuel 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:
  • Your top priority is to feel as comfortable as you can. Pick a pair of flat, closed-toe shoes, dress in loose, breathable clothing and remember to bring a pullover in case you get chilly in the cabin.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights.
How to get through airport security fast when flying to Dumbarton?
Being prepared before your flight will help make your getaway to Dumbarton a breeze. Here are some handy hints for a swift journey through security:
  • Be sure to keep your boarding pass and passport easily accessible. They're the first items you'll be asked for by security.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings like your belt, coat and headphones need to go through the machine.
  • All electronic devices, including your tablet and phone, will also need to be separately scanned.
  • Any gels or liquids, such as lip balm or cologne, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other heavy-style shoes are usually subjected to additional screening.
  • Sharp items are not allowed on board. They'll be seized at security, so pack them safely away in your checked bags.
