Frequently asked questions

How to book the cheapest flight to San Antonio?
If you want to save some cash on your trip to San Antonio, listen up! As every experienced jet-setter will tell you, don't book at the very last minute. Airfares are generally more expensive close to the departure date. Don't stop there, though. Do some research and see if there are multiple airports at your destination. Ticket prices often differ depending on the airport you go for. Remember to compare fares across air carriers too. Last of all, be prepared to secure your seat quickly if you stumble on a great price. It might not be available for too long! With a bit of knowledge and a little luck, the perfect fare can be yours.
Do you have any tips for my flight to San Antonio?
Depending on where you're coming from, your journey to San Antonio could be a breeze or it could go on forever. Below are some useful tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

  • Air travel can be a pleasure if you take the right stuff. Firstly, you'll want some toiletry items, such as deodorant and a toothbrush, a clean set of clothes and a magazine or two. Next, find a spot in your carry-on bag for your phone and charger, any vital medications and maybe a quality neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, aerosol cans and bleaching agents. Sports equipment like golf clubs, and items that could harm passengers, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on your flight. Loose, breathable clothing is a sensible option, as are flat, slightly roomy shoes.
  • Most travelers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lower your risk on board, stay hydrated, consider wearing compression socks or tights and move your lower limbs often.

How to get through airport security fast when flying to San Antonio?
A little pre-planning before you get to the airport will make your getaway to San Antonio a pleasure. Check out our handy tips and tricks for a swift journey past security:

  • Have your passport and travel documents easily accessible. They'll be the first things you'll be asked for by airport security.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronic gadgets, including your phone and laptop, are also required to be separately scanned.
  • Remove all gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • There's a good chance you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Sharp items such as knives and scissors are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked baggage.
