Cheap Flights to Austin from HK$4,454

If you're not prepared, air travel can be overwhelming. But there's no need to hit the panic button just yet. Follow these useful tips and enjoy a worry-free start to your getaway in Austin.What to pack in your hand luggage:

• It's easy — first, pack your passport, official ID, cash and medications. Next, you'll want some in-flight entertainment to while away the time. A juicy novel and a phone filled with your favorite movies are some great options. If you plan to take a quick snooze, a comfy neck pillow and some earplugs will also be useful. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you touchdown 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 liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Pointed or sharp objects, like your trusty Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also prohibited.

What to wear on a flight:

• The narrow aisles of an airplane are not the best place for a fashion parade. Layer up with comfy clothing and don't forget to bring a sweater as it tends to get cool in the cabin during long-haul flights. Slightly roomy, flat shoes are always a good choice too.
• The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-haul flights. But the good news is there are numerous ways to reduce your risk of developing it. Keep your fluids up, get up and walk around the cabin as much as possible and wear compression tights or socks.

As seasoned travelers know, the secret is to be well organized before you get to security. That way, you'll be hopping onto that plane to Austin in a flash. Follow these helpful tips and get your trip off to a terrific start:

• Security personnel first need to determine that you have a valid ID and matching travel documents before anything else. Have them in your hand, ready for inspection.
• The X-ray machine is up next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
• For just a few moments, you'll have to unplug from technology. Your laptop, phone and any other electronic devices will also need to be sent through the scanner.
• Traveling with your favorite cologne or perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on.
• Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and heavier-style shoes are often subjected to extra screening.
• Airlines won't allow any sharp or pointed objects in your hand luggage. If you need to bring these kinds of items, pack them in your checked luggage.
