### How long is the flight to Alton Airport? ### How to book the cheapest flight to Alton? ### Do you have any tips for my flight to Alton? > - The secret to having an amazing travel experience is to pack in advance. So, let's start with the basics: passport, travel documents, bank cards and important medications. Next, bring items that'll help keep you busy, like some electronic gadgets or a good read. It's also a wise idea to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to chuck in toiletries like a toothbrush, cleansing wipes and a clean T-shirt. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items can differ between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes knives, scissors, spray paint and flares. Sports equipment like bows and arrows, and items that could harm passengers, such as firearms and swords, can't come on board with you either. > > > What to wear on a flight: > > > - Your aim is to feel as comfortable as you can. Opt for flat, closed-toe shoes, dress in loose, breathable clothing and don't forget to bring a pullover in case you get chilly in the cabin. > - The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Reduce the risks by drinking water, keeping your legs moving and wearing compression socks to help your circulation. ### How to get through airport security fast when flying to Alton? > - Keep your ID and travel documents handy. They're the first items you'll be asked to show at security. > - Your coat, belt, keys and other items in your pocket, like coins, will be required to go through the X-ray machine. Make your life easier by removing them as your turn draws near. > - All your electronic gadgets, including your laptop and phone, must also be scanned separately. > - Remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag. > - The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes usually aren't. > - Avoid taking prohibited items in your carry-on bag.
