Last but not least, don't forget to chuck in toiletry items like a toothbrush, lip balm and a clean T-shirt. > > > Do not pack the following items in your hand luggage: > > > - Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your trusty pocket knife, and products which are explosive or flammable, such as flares, bleaching agents and fuels, are also banned. > > > What to wear on a flight: > > > - Your priority is to feel as comfortable as possible. Choose shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and don't forget to bring a jacket in case you get chilly in the cabin. > - The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs and feet moving and wearing compression socks or tights. ### How to get through airport security fast when flying to Grayslake? > - Your boarding pass and passport will need to be inspected by airport security. Have them easily accessible so you don't have to dig around for them. > - The X-ray machine is up next. Remove anything metal on you that is likely to set off the scanner's alarm.

Don't worry though, you'll be back online in no time. > - Want to bring along your favourite cologne or perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on baggage. > - Slip-on shoes are a great footwear choice as you're less likely to have to remove them when passing through security.
