Cheap Flights to Dublin from HK$4,386

If you're not prepared, airports and flying can be challenging. But there's no need to worry. Follow these handy hints for a worry-free start to your getaway in Dublin. What to pack in your hand luggage:

• Travelling on a plane can be a stress-free experience if you bring the right things. First things first, you'll need toiletry items, such as toothpaste, a toothbrush and some deodorant, a spare set of clothes and a good novel. Next, leave space in your carry-on bag for your phone and charger, your important medications and perhaps a neck pillow as well. Lastly, and most importantly, be sure to take your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a pocket knife hiding in the bottom of your carry-on luggage. Other banned items include explosive or flammable substances, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Comfort should be your highest priority when choosing what to wear on board. Loose clothing is a sensible option, as are flat, slightly roomy shoes.
• Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-distance flights. Reduce the risks by staying hydrated, keeping your lower limbs moving and wearing compression tights or socks.

Being prepared before you arrive at the airport will help make your trip to Dublin quick and painless. We've compiled some handy hints for a stress-free journey through security:

• Security personnel first need to verify that you have a valid ID and matching travel documents before you're allowed to proceed any further. Have them ready to show.
• Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• Your electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry though, you'll be back online in no time.
• Can't travel without your favourite hand and nail cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's OK to bring with you in your carry-on bag.
• There's a chance you'll be asked to take your shoes off for scanning, so wearing lightweight sneakers is always a good idea.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed in the cabin.
