Do you have any tips for my flight to Sunnyvale?

  • Get your trip off to the best start possible by being well prepared. Pack your passport, travel documents and any medications you need first. After that, think about downloading a few blockbuster movies on your tablet or phone for a binge session sans guilt. Or, bring that novel you’ve been wanting to read. Lastly, something to nibble on and a neck pillow will go a long way to making the flight as comfortable as possible.
  • Don’t forget there’s also a list of prohibited items for your hand luggage which differs between airlines. As a general rule, avoid packing anything sharp, explosive or flammable. This includes things like pocket knives, razor blades, flares and aerosol cans. Sports equipment like baseball bats, and objects that could harm passengers, such as batons and swords, are also banned from the cabin.

What to wear on a flight:

  • Go for comfort over fashion when flying. Layer up and wear natural materials since they allow moisture and air to pass through and keep you cool. Cabin temperatures typically get cooler on long-haul flights, so bring a pullover and always wear sneakers or enclosed shoes.
  • 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. Alternatively, do some lower limb exercises in your seat. If you’re at higher risk of developing DVT, consider wearing compression socks or tights.

If you want to grab a cheap last-minute flight to Sunnyvale, you’ll need to be flexible. If possible, have some wiggle room with the dates you plan to travel. It’s also wise to have a bit of flexibility with your departure and arrival airports, choice of airline, flight times and layovers or stops.
