Do you have any tips for my flight to Portsmouth?

  • Wherever your journey is taking you, flying can be a relaxing experience if you’re prepared. First, pack your passport (or a valid ID), travel documents and medications. Next, toss in some in-flight entertainment to help the time fly by. A juicy novel and a tablet filled with the latest movies are a couple of good options. If you want to get some shut-eye, a memory-foam neck pillow and noise-canceling headphones will also come in handy.
  • There’s also a list of prohibited items for your hand luggage which can differ between carriers and flight routes. As a general rule, avoid bringing anything explosive, flammable or sharp. 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 batons and swords, are also banned from the cabin.

What to wear on a flight:

  • Whether traveling long or short-haul, layering up is key to a comfy flight. Wear loose, breathable fabrics that will keep you cool and bring a sweater for any in-flight temperature changes. Your feet will be happiest in a pair of closed-toe shoes or sneakers.
  • Consider wearing compression socks or tights to reduce the risk of deep vein thrombosis (DVT). This blood clotting condition can be caused by prolonged periods of sitting, especially on long-haul flights. Performing foot and leg stretches in your seat or wandering around the cabin are good ways to improve your circulation.

How can I get a cheap last-minute flight to Portsmouth?
Finding a cheap, last-minute flight to Portsmouth is as easy as being flexible with your travel plans. Have some wiggle room when it comes to your choice of carrier, travel dates and flight times. If your destination has multiple airports, compare the prices of flying into each of them for the best deal on your airfare.
