Do you have any tips for my flight to Oceanside?
Wherever you're jetting in from, flying can be an enjoyable experience if you've planned ahead. We've put together a list of handy tips that will help get your Oceanside holiday started on the right foot. What to pack in your hand luggage:
  • First, put in your passport, official ID, credit cards and medications. Next, you'll want some extra in-flight entertainment to help pass the time. A thrilling novel and a tablet filled with your favourite shows are some fantastic options. If you plan to take a short nap, a quality neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a few toiletry items so you'll hop off the plane looking fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Make sure you don't have a Swiss Army knife hiding in one of the zippers of your carry-on luggage. Other prohibited items include explosive or flammable products, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • The aisles of an airplane aren't the place for a fashion parade. Dress in comfortable layers and pick shoes that are closed-toe, flat and easy to take on and off.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to Oceanside?
It's all about being organised. We've compiled some top tips for a speedy trip through airport security. Look out Oceanside, here you come:
  • Keep your ID and travel documents within close reach. They'll be the first things you'll be asked to present to security.
  • Time to strip down. Well sort of. Your belt, coat, keys and other small items, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them before your turn arrives.
  • All your electronic gadgets, including your laptop and phone, are also required to be scanned.
  • Remove all gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Airlines will not allow any pocket knives or other sharp items in your carry-on luggage. If you need to bring these kinds of items, pack them in your checked luggage.
