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

  • Get your trip off to an excellent start by being well prepared. Pack your travel documents, passport and medications first. After that, consider downloading the latest TV series on your tablet or phone for a guilt-free binge session. Or, bring that bestseller you haven’t had time to read. Lastly, something to nibble on and a good neck pillow will go a long way to making your journey as comfortable as possible.
  • You’ll also want to check with your airline regarding what you can’t take on board your flight. Batons, swords, box cutters, razor blades and knives are among the prohibited items. Anything flammable, explosive or sharp is generally not allowed in your carry-on bag. Be sure to pack any sports equipment like baseball bats or tennis rackets in your checked luggage.

What to wear on a flight:

  • Whether traveling long or short-haul, layering up is key to a comfortable flight. Wear loose fitting, breathable fabrics that will keep you fresh and bring a sweater to cope with any in-flight cabin temperature changes. Your feet will be happiest in a pair of closed-toe shoes or sneakers.
  • The condition called deep vein thrombosis (DVT) is a risk on long-distance flights. It’s the result of blood clotting due to inactivity and poor circulation. Walking up and down the aisle and doing leg and foot exercises while seated can prevent it developing. Wearing compression socks or tights can also help to lessen your risk.

How can I get a cheap last-minute flight to San Marcos?
To pick up a cheap last-minute flight to San Marcos, being flexible is key. If possible, have some wiggle room with the dates you plan to fly. It will also help to have a bit of flexibility with your departure and arrival airports, choice of carrier, flight times and stops or layovers.
