We've pulled together all the info you need to make your flight an enjoyable experience. Follow our insider tips and you'll be breezing through the airport and exploring Southwest in next to no time.What to pack in your hand luggage:

• It's simple — first, pack your passport, important documents, credit cards and vital medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling novel and a tablet crammed with your favorite shows are some wonderful options. If you hope to take a quick nap, a quality neck pillow and some noise-canceling headphones will also be useful. Finally, leave space for a few toiletry items so you'll hop off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a sharp object lurking in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The goal here is to be as comfortable as possible. Layer up with loose, natural-fiber clothing and don't forget to pack a sweater in case it gets chilly in the cabin. Go for a pair of roomy, flat shoes as your feet may swell during the journey. Leave the high heels and heavy boots in your checked luggage.
• The serious condition known as DVT (deep vein thrombosis) can pose a risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity. Walking around the cabin and doing regular foot and leg exercises in your seat helps to prevent this from happening. Wearing a good-quality pair of compression tights or socks is also a wise idea.

As savvy travelers know, the secret is to be prepared before you reach airport security. That way, you'll be hopping onto that plane to Southwest in next to no time. Follow these tips and get your trip off to a great start:

• Your ID and travel documents will need to be inspected by airport security. Keep them handy so you don't hold up the queue.
• Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Items like your jacket, belt and earphones need to go through the machine.
• For just a few minutes, you'll need to unplug from the digital world. Your phone, laptop and any other electronics will also need to go through the scanner.
• Traveling with your favorite cologne or perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you can keep it with you in your carry-on baggage.
• It's also possible you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a wise idea.
• Airlines will not allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, check them in.
