Do you have any tips for my flight to Tha Sai?
Depending on where you're coming from, your trip to Tha Sai could be completely painless or it could go on forever. We've put together some useful travel tips that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

  • First of all, pack your passport, official ID, wallet and vital medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a tablet filled with your favourite movies are some wonderful options. If you intend to take a quick nap, a comfy neck pillow and some earplugs will also come in handy. Finally, leave some space for a toothbrush and some cleansing wipes so you'll arrive at your destination looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your precious pocket knife, and products which are flammable or explosive, such as flares, chemicals agents and matches, are also prohibited.

What to wear on a flight:

  • Your main priority is to feel as comfortable as possible. Go for shoes that are easy to slip on and off, dress in loose, breathable clothing and don't forget to take a sweater in case it gets cold in the cabin.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression socks and keep your legs and feet moving.

How to get through airport security fast when flying to Tha Sai?
The trick is to be organised before you reach airport security. That way, you'll be hopping onto that plane to Tha Sai in next to no time. Follow these helpful tips and get your holiday off to a terrific start:

  • Your passport and travel documents will need to be shown to airport security. Keep them at hand so you don't hold up the line.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your coat, belt and earphones need to go through the machine.
  • Electronic devices like phones and laptops will also have to go on a tray for inspection. Don't worry though, you'll be back online in no time.
  • Any liquids or gels, such as perfume or hairspray, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you need to bring these kinds of items, put them in your checked baggage.
