Do you have any tips for my flight to Underwood?
If you're not prepared, travelling can be daunting. But there's no need to worry. Follow these handy tips for a stress-free start to your holiday in Underwood. What to pack in your hand luggage:

  • Firstly, and most importantly, put in your passport, important documents, cash and daily medications. Next, you'll want some in-flight entertainment to while away the hours. A thrilling book and a tablet filled with your favourite shows are always good options. If you hope to catch forty winks, a quality neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes so you'll arrive feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as flares, bleaching agents and fuels, are also restricted.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Layer up with comfy clothing and opt for shoes that are closed-toe, flat and easy to take on and off.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Underwood?
A little pre-planning before your flight will make your getaway to Underwood a piece of cake. Read through our useful tips for a swift journey past security:

  • First things first. Your boarding pass and passport will need to be inspected by security personnel. Keep them someplace accessible so you don't hold up the queue.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings like your belt, jacket and earphones will be required to go through the machine.
  • Your electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry, you'll be back online in no time.
  • Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when passing through security. Boots and other heavy-style shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, put them in your checked baggage.
