Do you have any tips for my flight to Dupo?
- A plane ride can be a great experience if you take the right things. First things first, you'll need toiletry items, such as a toothbrush and hairbrush, a spare change of clothes and a magazine or two. Secondly, make room in your carry-on bag for your laptop, a charger, any medications and perhaps a cosy neck pillow as well. Lastly, don't forget to take your passport, travel documents and your credit cards.
- While the list of prohibited items can differ between airlines, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, drills, spray paint and flares. Sports equipment like ski poles, and items that could harm passengers, such as firearms and ammunition, won't be allowed on board either.
- Your top priority is to feel as comfortable as possible. Pick a pair of flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to bring a jacket in case it gets chilly in the cabin.
- Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lower your risk on board, drink plenty of water, consider wearing compression socks and keep your feet and legs moving.
How to get through airport security fast when flying to Dupo?
- Be sure to have your travel documents and ID within close reach. They're the first items you'll be asked for by airport security.
- After that, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings such as your belt, coat and headphones will be required to go through the machine.
- For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronic devices will need to be sent through the scanner.
- Remove all liquids and gels from your hand luggage. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
- Slip-on shoes are a good footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy shoes are often subjected to extra screening.
- Sharp items like knives are not allowed on board. They'll be seized at security, so pack them in your checked bags.
