Do you have any tips for my flight to Rancho Santa Margarita?
No matter where you're coming from, flying can be an enjoyable experience if you've planned ahead. Take a peek at these top travel tips that will get your Rancho Santa Margarita vacation started on the right note. What to pack in your hand luggage:

  • A plane ride can be a comfortable experience if you pack the right gear. First of all you'll need basic toiletries, such as a toothbrush and lip balm, a clean pair of socks and a good novel. Next, leave space in your bag for your phone, tablet and chargers, your important medications and maybe a quality neck pillow as well. Lastly, and most importantly, don't forget to take your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, fuel and fireworks. Sporting equipment like bows and arrows, and items that could injure passengers, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

  • Your aim here is to be as comfortable as possible. Pick a pair of flat, closed-toe shoes, dress in loose, natural-fiber clothing and remember to bring a pullover in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Rancho Santa Margarita?
A little pre-planning before you get to the airport will make your trip to Rancho Santa Margarita quick and painless. Read through our handy tips for a stress-free journey through security:

  • Airport security personnel first need to establish that you have a valid passport and matching travel documents before you're allowed to proceed any further. Keep them close by.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to beep. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online in no time.
  • Don't forget to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-lock bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy-style shoes are usually subjected to additional screening.
  • Sharp or pointed items can't be taken on board. They'll be confiscated at security, so pack them in your checked baggage.
