Frequently asked questions

How to book the cheapest flight to San Antonio?
We all know those lucky jet-setters who somehow pick up impossibly cheap plane tickets wherever they go. Would you like to know how to do it for your San Antonio vacation? Don't wait until the last minute to secure your flight. Another terrific way to grab the most affordable fare is to compare all options. If your destination has several airports, research the cost of flying into a less busy terminal. Lastly, be prepared to lock in your seat quickly if you stumble on a real bargain. It might not be available for too long. With a bit of know-how and some good fortune, the ideal fare can be yours.
Do you have any tips for my flight to San Antonio?
Wherever you're jetting in from, flying can be a seamless experience if you're well organized. We've put together a list of handy travel tips that will help get your San Antonio vacation started on the right foot. What to pack in your hand luggage:

  • First of all, pack in your passport, important documents, cash and vital medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy book and a tablet crammed with your favorite movies are some fantastic options. If you intend to catch up on some sleep, a neck pillow and some noise-canceling headphones will also be useful. Finally, leave some space for a few toiletry items so you'll arrive 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 conditioner in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your pocket knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and strong acids, are also not allowed.

What to wear on a flight:

  • Comfort should be your top priority when choosing what to wear on your flight. Loose, breathable clothing is a wise option, as are flat, closed-toe shoes.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to San Antonio?
Being organized before you get to the airport will help make your trip to San Antonio quick and painless. We've rounded up some top tips for a stress-free journey through security:

  • Have your travel documents and ID handy. They'll be the first things you'll be asked to present to security.
  • Your jacket, belt, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronics will need to go through the scanner.
  • Any gels or liquids, such as toothpaste or perfume, that you want to take on board need to be in containers no larger than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Airlines will not allow any sharp objects to come on board with you. If you must bring these kinds of items, pack them in your checked baggage.
