This includes things like screwdrivers, blades, fuel and fireworks. Sporting equipment like golf clubs, and objects that could harm other people, such as pepper spray and firearms, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - The narrow aisles of an aircraft are no place for a fashion parade. Layer up with comfy clothing and pack a sweater as it can get chilly in the cabin on long-haul flights. Slightly roomy, flat shoes are also recommended. > - Unfortunately, a risk of long-haul flights is developing deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity. To prevent this from happening, make the most of every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are another great idea to help minimize this risk. ### How to get through airport security fast when flying to Castle Danger? > - Security personnel first need to determine that you have a valid ID and travel documents before you can proceed any further.

Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag. > - It's also possible you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea. > - Airlines won't allow any sharp or pointed objects in your carry-on baggage.
