Start with the essentials: passport, travel documents, bank cards and any vital medications. Next, take on board items that'll help keep you occupied, like some electronic gadgets or a magazine. It's also wise to bring your chargers, a quality neck pillow and a pair of earphones. Finally, be sure to squeeze in toiletry items like a toothbrush, deodorant and a fresh change of clothes. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items differs between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, knives, spray paint and fireworks. Sporting equipment like ice skates, and items that could injure passengers, such as swords and batons, can't come on board with you either. > > > What to wear on a flight: > > > - Go for comfort over style. Prepare for changes in temperature by layering up, and pick slightly roomy, flat shoes like slip-ons. > - Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Cardiff-by-the-Sea? > - Security personnel first need to establish that you have a valid ID and matching travel documents before you can proceed any further. Have them in your hand, ready for inspection. > - Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. Don't worry though, you'll be back online in no time. > - Want to bring along your favourite perfume? No problem. 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 OK to bring with you in your carry-on bag. > - There's a chance you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a good idea. > - Airlines won't allow any sharp or pointed objects in the cabin. If you must bring these kinds of items, pack them in your checked luggage. __Flights to Cardiff-by-the-Sea information__ | Destination airport | San Diego Intl. | | ----------------------------- | --------------- | | Destination airport IATA code | SAN | | Destination city name | San Diego | | Return price | £82 | ## Trending flights to Cardiff-by-the-Sea Prices were available within the past 7 days and start at £328 for one-way flights and £414 for round trip, for the period specified.
