Do you have any tips for my flight to Portsmouth?

  • What you pack in your carry-on baggage can be the difference between a comfortable flight, and a not-so-great one. Start with the crucial things, like your passport (or a valid ID) and your travel documents. Once they’re packed, toss in any medications you might need. Next? It’s all about the comfort factor. Earplugs, a neck pillow and a good book will help the time fly by while you’re in your seat.
  • Don’t forget there’s also a list of prohibited items for your hand luggage which differs between carriers. Generally, avoid bringing anything flammable, explosive or sharp. This includes things like razor blades, box cutters, flares and aerosol cans. Sports equipment like baseball bats, tennis rackets 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 before fashion when flying. Layer up and wear natural fabrics as they allow moisture and air to pass through and keep you cool. Cabin temperatures can get cold on long-haul flights, so pack a pullover and always wear sneakers or enclosed shoes.
  • The condition known as deep vein thrombosis (DVT) is a risk on long-distance flights. It’s the result of blood clotting caused by poor circulation and inactivity. Walking up and down the aisle and doing foot and leg stretches while seated can prevent it developing. Wearing compression tights or socks also helps to lessen your risk.

How can I get a cheap last-minute flight to Portsmouth?
The key to securing a cheap last-minute flight to Portsmouth is flexibility. You can snap up a fabulous deal if you’re not tied to specific travel dates, flight times and carriers. Also compare the prices of flying into and out of nearby airports if that’s an option for you.
Where can I learn more about changing or canceling my flight to Portsmouth?
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.
