Do you have any tips for my flight to San Marcos?

  • What you pack in your carry-on baggage can make the difference between a comfortable flight, and a not-so-great one. Start with the important stuff, like your passport (or a valid ID) and your travel documents. Once they’re safely packed, throw in any medications you might need. Next, think about comfort factor. A quality neck pillow, earplugs and a juicy bestseller will help the hours fly by while you’re in your seat.
  • There’s also a list of prohibited items for your hand luggage which can differ between airlines. Generally, avoid carrying anything flammable, sharp or explosive. This includes things like razor blades, box cutters, aerosol cans and flares. Sporting equipment like baseball bats, ski poles and objects considered weapons, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

  • The aisles of a plane aren’t designed for a fashion parade. Layer up in comfy clothing and bring a pullover since it can get cool in the cabin on long-haul flights. Sneakers or other closed-toe shoes are perfect for longer journeys.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for long periods of time, by regularly moving around the cabin. Otherwise, do foot and leg exercises in your seat. If you’re at higher risk of developing DVT, consider wearing compression socks.

How can I get a cheap last-minute flight to San Marcos?
The key to getting a cheap, spur-of-the-moment flight to San Marcos is to be flexible. You can increase your chances of landing an awesome deal if you’re not tied to particular airlines, flight times and travel dates. Also compare the prices of flying out of and into alternative airports if that’s an option for you.
Where can I learn more about changing or canceling my flight to San Marcos?
