This includes things like screwdrivers, blades, aerosol cans and bleaching agents. Sporting equipment like hockey sticks, and objects that could harm passengers, such as firearms and swords, won't be allowed on board either. > > > What to wear on a flight: > > > - Comfort should be your highest priority when deciding what to wear on your flight. Loose clothing is a smart option, as are flat, slightly roomy shoes. > - Deep vein thrombosis (DVT) is a risk on long-haul flights.

They're the first things 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 is likely to trigger the alarm. Personal belongings like your belt, jacket and earphones will be required to go through the machine. > - For just a few moments, you'll have to unplug from technology. Your laptop, phone and any other electronic devices must also go through the scanner. > - Any gels or liquids, such as perfume or toothpaste, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag. > - There's a chance you'll be required to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea. > - Airlines will not allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, put them in your checked luggage. ## Book with confidence # Expedia flights to San Antonio Searching for cheap flights to San Antonio?
