Next, you'll need some extra in-flight entertainment to help pass the time. A juicy book and a laptop crammed with your favourite shows are some fantastic options. If you plan to take a short nap, a neck pillow and some earplugs will also be useful. Finally, find room for a toothbrush and some cleansing wipes to ensure you touchdown looking fresh and raring to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items can differ between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes things like box cutters, razor blades, fuel and fireworks. Sporting equipment like baseball bats, and items that could harm passengers, such as pepper spray and firearms, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - The best way to ensure a comfortable flight often lies in the clothes you wear. Prepare yourself for varying temperatures by layering up. That way you'll stay nice and warm if the cabin gets too cold. Shoes like stilettos, flip flops and lace-up boots are best left in your suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will thank you later. > - You've probably heard about DVT (deep vein thrombosis), a blood clotting condition caused by long periods of sitting. There are numerous ways to lessen your risk. Wear a quality pair of compression socks or tights, drink lots of water often and keep your legs and feet moving. Wander up and down the aisles of the cabin or perform some stretches in your seat. ### How to get through airport security fast when flying to Sullivan? > - Your travel ID and boarding pass will need to be inspected by airport security personnel. Keep them someplace accessible so you don't hold up the line. > - The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening. > - For just a few moments, you'll have to unplug from technology. Your phone, laptop and any other electronic devices will also need to be sent through the scanner. > - Any gels or liquids, such as perfume or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), clear zip-close bag. > - Choosing your footwear wisely can save you several valuable minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers are usually not. > - Sharp items like knives can't be taken on board. They'll be confiscated at security, so pack them safely away in your checked suitcase. __Flights to Sullivan information__ | Destination airport | University Of Illinois Urbana-Champaign Williard | | ----------------------------- | ------------------------------------------------ | | Destination airport IATA code | CMI | | Destination city name | Champaign | | Return price | £844 | ## Trending flights to Sullivan Prices were available within the past 7 days and start at £537 for one-way flights and £844 for round trip, for the period specified.
