Next, you'll want some in-flight entertainment to help pass the time. A juicy novel and a laptop filled with your favourite shows are good options. If you hope to catch a few z's, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, make room for a few toiletry items so you'll arrive at your destination looking fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items can differ between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, drills, aerosol cans and bleaching agents. Sports equipment like ski poles, and objects that could injure passengers, such as pepper spray and firearms, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - The aisles of an airplane aren't the place for a fashion parade. Layer up with comfortable clothing and go for shoes that are flat, enclosed and easy to take on and off. > - It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lower your risk on board, stay hydrated, consider wearing compression socks and keep your legs and feet moving. ### How to get through airport security fast when flying to Clear Lake? > - Your passport and travel documents will need to be inspected by airport security personnel. Have them close by to avoid fumbling around for them. > - Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. This includes things like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening. > - For just a few minutes, you'll have to unplug from the digital world. Your laptop, phone and any other electronic gadgets will need to be sent through the scanner. > - Travelling with a new cologne? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on bag. > - Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Boots and heavier-style shoes are often subjected to additional screening. > - Sharp or pointed items are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked baggage. __Flights to Clear Lake information__ | Destination airport | Watertown Regional | | ----------------------------- | ------------------ | | Destination airport IATA code | ATY | | Destination city name | Watertown | | Roundtrip price | CA $259 | ## Trending flights to Clear Lake Prices were available within the past 7 days and start at CA $127 for one-way flights and CA $259 for round trip, for the period specified.
