Do you have any tips for my flight to El Cajon?

  • What you pack in your carry-on bag can be the difference between a comfortable flight, and one you’d rather forget. Start with the important stuff, like a valid ID (like your passport) and your travel documents. Once they’re safely packed, put in any medications you might need. After that, consider your comfort factor. Earplugs, a quality neck pillow and a novel will help the time fly by while you’re soaring through the sky.
  • There’s also a list of prohibited items for your hand luggage which can differ between airlines. As a general rule, avoid bringing anything explosive, sharp or flammable. This includes things like razor blades, utility knives, aerosol cans and flares. Sports equipment like ski poles, baseball bats and objects that could harm passengers, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

  • Choose comfort rather than fashion when flying. Dress in layers and wear natural fabrics since they allow moisture and air to pass through and keep you cool. Cabins can get colder on longer journeys, so pack a hoodie or similar and always wear sneakers or enclosed shoes.
  • The condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting due to inactivity and poor circulation. Strolling up and down the aisle and doing foot and leg exercises while seated can prevent it developing. Wearing compression tights or socks also helps reduce your risk.

How can I get a cheap last-minute flight to El Cajon?
Finding a cheap, spur-of-the-moment flight to El Cajon is as easy as being flexible with your travel plans. Have some leeway with your choice of airline, travel dates and flight times. If your destination has a few airports to choose from, compare the prices of flying into each of them for the best airfare deals.
Where can I learn more about changing or canceling my flight to El Cajon?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
