Do you have any tips for my flight to O Brien?
We've pulled together all the info you need to make your journey as pain-free as possible. Follow our insider tips and you'll be hightailing it through airport security and having a blast in O Brien in no time. What to pack in your hand luggage:
  • First of all, pack your passport, travel docs, wallet and vital medications. Next, you'll need some extra in-flight entertainment to while away the hours. A thrilling book and a tablet crammed with your favourite movies are good options. If you plan to catch up on some sleep, a quality neck pillow and some earplugs will also come in handy. Finally, leave space for a toothbrush and some deodorant so you'll hop off the plane looking fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of shampoo 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 by security. Sharp objects, like a Swiss Army knife, and products which are explosive or flammable, such as flares, chemicals agents and fuels, are also prohibited.
What to wear on a flight:
  • Choose comfort over style. Prepare for temperature changes by layering up, and pick closed-toe, flat footwear like slip-ons.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.
How to get through airport security fast when flying to O Brien?
The trick is to be well organized before you arrive at the airport security gate. That way, you'll be stepping onto that plane to O Brien in next to no time. Follow these tips and get your trip off to a fantastic start:
  • Security personnel first need to establish that you have a valid ID and boarding pass before you can proceed any further. Keep them close by.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your tablet and phone, are also required to be separately scanned.
  • Want to bring along your favourite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're allowed to bring it with you in your carry-on baggage.
  • The right choice of footwear can save you valuable minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed in the cabin.
