Do you have any tips for my flight to Oceanside?
Wherever you're jetting in from, flying can be a seamless experience if you've prepared well enough. Take a peek at these handy tips and tricks that will help get your Oceanside vacation started on the right foot. What to pack in your hand luggage:
  • Flying can be a cruisy experience if you pack the right things. Firstly, you'll want some basic toiletry items, such as lip balm and hand cream, a fresh set of clothes and a good book. Secondly, leave space in your bag for your laptop, a charger, any daily medications and perhaps a blow-up neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and your credit cards.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your beloved pocket knife, and dangerous goods which are flammable or explosive, such as flares, chemicals agents and poisons, are also restricted.
What to wear on a flight:
  • You'll want to choose comfort over style. Prepare for changes in temperature by donning layers, and wear flat, closed-toe footwear like sneakers.
  • You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lower your risk on board, stay hydrated, consider wearing compression socks and keep your feet and legs moving.
How to get through airport security fast when flying to Oceanside?
The simple answer is — be prepared. We've put together some helpful hints for a fuss-free trip through security. Look out Oceanside, here you come:
  • Security personnel first need to establish that you have a valid passport and matching travel documents before you can proceed any further. Have them in your hand, ready for inspection.
  • Next up, both you and your carry-on bag will be X-rayed. To speed things up, remove anything that might set the alarms off. Items like your coat, belt and headphones need to go through the machine.
  • All your electronic gadgets, including your tablet and phone, will also need to be scanned separately.
  • Travelling with your favourite hand cream? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you on board.
  • Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when going through security. Big boots and other heavy shoes are often subjected to extra screening.
  • Sharp or pointed items can't be taken on board. They'll be seized at security, so pack them safely away in your checked suitcase.
