Do you have any tips for my flight to Allentown?
If you're poorly prepared, traveling can be tough. But there's no need to hit the panic button just yet. Follow these handy hints and enjoy a pleasant start to your vacation in Allentown. What to pack in your hand luggage:

  • Flying can be a great experience if you bring the right gear. Firstly, you'll want some basic toiletries, such as deodorant and a toothbrush, a fresh set of clothes and a good book. Secondly, make room in your hand luggage for your laptop, a charger, any vital medications and maybe a blow-up neck pillow as well. Lastly, be sure to bring your passport, travel documents and your bank cards.

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 liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Pointed or sharp objects, like your treasured Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, flares and strong acids, are also banned.

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfortable clothing and choose shoes that are flat, enclosed and easy to pull on and off.
  • 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 Allentown?
As savvy travelers know, the secret is to be well organized before you reach airport security. That way, you'll be hopping onto that plane to Allentown in no time flat. Follow these tips and get your vacation off to a spectacular start:

  • Security personnel first need to determine that you have a valid ID and travel documents before you're allowed to proceed any further. Have them within easy reach, ready for inspection.
  • The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes things like headphones or earphones, 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 phone and tablet, are also required to be scanned separately.
  • Can't travel without your favorite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's OK to bring with you on board.
  • Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Airlines won't allow any sharp objects in your carry-on luggage. If you need to bring these kinds of items, put them in your checked baggage.
