1. Wear Comfortable Clothing. It is so important to feel comfortable at the Airport as you are likely to be waiting around a lot before your flight. Even though you need to feel comfortable though it doesn't mean you have to sacrifice your sense of style!- Wear stylish clothes and accessorise with non-metal bracelets or necklaces etc. Also make sure that you wear shoes that are easy to slip on and off as it is likely that they will be scanned separately in security. Flip Flops are a no-go. Think about how many people stand in the security line at the airport. Now, think about swapping germs with all of them...eww! Where shoes you can wear socks with to avoid walking bare-footed on the airport floor and protect your toes from being trampled. And girls, save the 5" heels to wear at your destination; trust me, you don't want to be painfully stumbling around a crowded Airport!
2. Don't Wear an Underwire Bra. The wire in your underwire bra will trigger the sensitive airport metal detectors which could lead to an uncomfortable and slightly embarrasing 'pat-down' inspection. Opt for a bra that gives you support as well as comfort - and won't get you stopped at security or dig into your back and shoulders during a long flight.
3. Wear Layers. Its a very efficient and sensible idea to layer your clothing when going to an Airport. The coolness/heat may vary depending on the amount of air conditioning so you'll want to be able to easily strip down if you get too hot and vice versa...However, don't wear very bulky or thick items of clothing as this may look suspicious to security members and could lead to a thorough pat down inspection! Bring a Pashmina. You can use it as a blanket, a scarf and eye mask...It's so useful!
I hope you take this advice and have a safe and comfortable journey.
Good Luck at the Airport!
