Firstly, you'll want some basic toiletry items, such as deodorant, toothpaste and a toothbrush, a spare pair of socks and a good read. Next, leave space in your hand luggage for your phone, tablet and chargers, your important medications and perhaps a comfy neck pillow as well. Last, but definitely not least, remember to take your passport, travel papers and some cash. > > > Do not pack the following items in your hand luggage: > > > - Make sure you don't have a sharp object lurking in one of the compartments of your hand luggage. Other banned items include flammable or explosive goods, such as fuel and matches, and liquids and gels in containers larger than 3.4 ounces (100 milliliters). > > > What to wear on a flight: > > > - The narrow aisles of an aircraft are not the place for a fashion parade. Wear comfortable clothes and bring a cardigan as it can get quite cool in the cabin. Flat, enclosed shoes are also a good choice. > - A condition known as DVT (deep vein thrombosis) is a risk on long-haul flights. It results from blood clotting due to poor circulation. Walking around the cabin and doing regular leg and foot exercises while seated helps to prevent this happening. Wearing a good pair of compression socks or tights is also recommended. ### How to get through airport security fast when flying to Alder? > - Security personnel first need to determine that you have a valid passport and travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection. > - The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. 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. > - For just a few moments, you'll have to unplug from the digital world. Your phone, laptop and any other electronics also need to go through the scanner. > - Remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag. > - It's also likely that you'll need to take your shoes off for scanning, so wearing slip-on shoes is always a wise idea. > - Airlines won't allow any pocket knives or other sharp items in the cabin. If you need to bring these kinds of items, pack them in your checked luggage. \*Flight schedules are subject to change. ## Book with confidence # Tips to find the cheapest flights to Alder **The cheapest day to fly** Get started finding a cheap flight to Alder on Expedia by either choosing a deal on this page or entering into the search bar your travel dates, origin airport, and whether you want roundtrip or one-way airfare.
