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

  • Get your vacation off to a good start by being prepared. Pack your travel documents, passport and medications first. Next, consider downloading the latest movies on your tablet or phone for a sans-guilt binge session. Or, toss in that juicy novel you haven’t had time to read. Lastly, a few tasty snacks and a good-quality neck pillow will help make your flight as comfortable as possible.
  • There’s a list of items you should not pack in your carry-on too. Explosives, flammables and sharps are strictly prohibited in the cabin — they often include box cutters, razor blades, aerosol cans and flares. Some sporting equipment, like martial arts weapons and baseball bats, are also not allowed in your hand luggage. Your airline’s website will have all the details about what you can and can’t bring on board.

What to wear on a flight:

  • The aisles of an aircraft aren’t suitable for a fashion show. Layer up with comfortable clothing and pack a hoodie since it can get cool in the cabin during long-haul flights. Sneakers or other closed-toe shoes are perfect for longer journeys.
  • Lessen 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, perform foot and leg exercises in your seat. If you’re at higher risk of developing DVT, consider wearing compression socks.
