This includes screwdrivers, blades, spray paint and fireworks. Sporting equipment like ice skates, and objects that could harm passengers, such as guns and swords, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - Comfort really should be your main priority when selecting what to wear on board. Consider your footwear choice carefully too, as swelling of the feet and ankles are a common side effect of flying. Slightly roomy, flat shoes work well. > - Most travelers are aware of DVT (deep vein thrombosis), a blood clot condition caused by long periods of sitting. There are plenty of ways to reduce your risk. Wear a pair of compression socks or tights, drink plenty of water and remember to keep your legs and feet moving. Wander up and down the aisles of the cabin or try out some simple stretches in your seat. ### How to get through airport security fast when flying to Castle Point? > - Be sure to have your ID and travel documents close by.

Not a problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on. > - Lightweight sneakers are a practical footwear choice as you're less likely to be required to remove them when going through security. Big boots and heavier-style shoes are usually subjected to additional screening. > - Airlines won't allow any sharp or pointed objects in your carry-on baggage. If you need to bring these kinds of items, pack them safely in your checked baggage. \*Flight schedules are subject to change. ## Book with confidence # Tips to find the cheapest flights to Castle Point **The cheapest day to fly** Get started finding a cheap flight to Castle Point 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.
