How to survive the flight to San Antonio?
If you’re not prepared, traveling can be testing. But there’s no need to worry. Follow these handy hints for a worry-free start to your vacation in San Antonio.What to pack in your hand luggage:

  • It’s simple — first, put in your passport, travel docs, wallet and medications. Next, you’ll need some extra in-flight entertainment to while away the time. A thrilling book and a phone filled with your favorite shows are good options. If you plan to take a quick snooze, a comfy neck pillow and some noise-canceling headphones will also be useful. Finally, make room for a few toiletry items to ensure you step off the plane 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 luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as aerosols and strong acids, are also restricted.

What to wear on a flight:

  • The aisles of a plane are not the place for a fashion parade. Wear comfortable clothes and remember to take a sweater as it can get quite cool inside the cabin. Closed-toed, flat shoes are also a good choice.
  • You’ve probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. There are plenty of ways to reduce your risk. Wear a good-quality pair of compression socks or tights, drink lots of water often and move your legs and feet. Do a lap or two of the cabin or perform exercises in your seat.

How to get through airport security fast when flying to San Antonio?
The answer is simple — be organized. We’ve rounded up some handy tips and tricks for an easy trip through airport security. Look out San Antonio, here you come:

  • Have your ID and travel documents someplace easily accessible. They’ll be the first things you’ll be asked for by airport security.
  • 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 the digital world. Your phone, laptop and any other electronics must also be sent through the scanner.
  • Can’t travel without your favorite cologne or perfume? As long as it’s in a container no larger 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.
  • The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren’t.
  • Airlines won’t allow any sharp items or pocket knives in your hand luggage. If you need to bring these kinds of items, put them in your checked baggage.
