First of all you'll need basic toiletries, such as deodorant and a toothbrush, a clean pair of socks and a good book. Secondly, make room in your carry-on bag for your electronic gadgets, chargers, medications and perhaps a cosy neck pillow as well. Lastly, don't forget to take your passport, travel papers and some cash. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have a Swiss Army knife hiding in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive goods, such as fuel and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - You'll want to choose comfort over style. Prepare for changes in cabin temperature by dressing in layers, and wear flat, closed-toe shoes like slip-ons. > - Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Round Lake? > - Keep your passport and boarding pass within easy reach. They're the first items you'll be asked to present to airport security. > - After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items such as your coat, belt and headphones will be required to go through the machine. > - All your electronic gadgets, including your laptop and phone, will also need to be separately scanned. > - Don't forget to remove gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag. > - Lightweight sneakers are a good footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other bulky shoes are often subjected to additional screening. > - Sharp or pointed items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked baggage. __Flights to Round Lake information__ | Destination airport | O'Hare Intl. | | ----------------------------- | ------------ | | Destination airport IATA code | ORD | | Destination city name | Chicago | | Return price | £396 | ## Trending flights to Round Lake Prices were available within the past 7 days and start at £305 for one-way flights and £397 for round trip, for the period specified.
