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

  • What you pack in your cabin baggage can mean the difference between a comfortable flight, and a restless one. Start with the essentials, such as a valid ID (like your passport) and your travel documents. Once they’re packed, toss in any medications you might need. Next? It’s all about comfort factor. A neck pillow, noise-canceling headphones and a juicy novel will help the time fly by while you’re soaring above the clouds.
  • Don’t forget there’s also a list of prohibited items for your hand luggage which can differ between airlines and routes. As a general rule, avoid carrying anything explosive, sharp or flammable. This includes things like razor blades, pocket knives, aerosol cans and flares. Sporting equipment like baseball bats, ski poles and objects that could harm passengers, such as batons and swords, are also banned from the cabin.

What to wear on a flight:

  • Choose comfort before fashion when flying. Layer up and wear natural fabrics as they allow air and moisture to pass through and keep you cool. Cabin temperatures can get cold on long-haul flights, so bring a hoodie or similar and always wear sneakers or flat, closed-toe shoes.
  • The condition called deep vein thrombosis (DVT) is a risk on long-distance flights. It’s the result of blood clotting caused by inactivity and poor circulation. Walking up and down the aisle and doing leg and foot exercises while seated can help prevent this developing. Wearing compression socks or tights can also help to lessen your risk.

How can I get a cheap last-minute flight to San Diego?
If you want to land a cheap last-minute flight to San Diego, flexibility is key. If you can, have some wiggle room with the dates you plan to fly. It’s also wise to have a bit of flexibility with your airports, airline choice, flight times and potential layovers or stops.
Where can I learn more about changing or canceling my flight to San Diego?
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.
