Do you have any tips for my flight to New Castle?

  • What you pack in your cabin baggage can mean the difference between a comfortable flight, and a not-so-great one. Start with the most important stuff, like a valid ID (like your passport) and your travel documents. Once they’re safely packed, put in any medications you might need. Next? It’s all about the comfort factor. Earplugs, a neck pillow and a book will help the hours fly by while you’re soaring through the sky.
  • There’s a lengthy list of items you shouldn’t pack in your carry-on bag too. Sharps, explosives and flammables are strictly prohibited in the cabin — they often include knives, razor blades, flares and aerosol cans. Some sporting equipment, such as baseball bats and martial arts weapons like nunchucks, also generally can’t go in your hand luggage. Check your airline’s website for details about what you can and can’t take on board.

What to wear on a flight:

  • The aisles of an aircraft aren’t suitable for a fashion show. Layer up in comfy clothing and pack a sweater as it can get cool in the cabin during long-haul flights. Enclosed, flat shoes are ideal for longer journeys.
  • The condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting caused by inactivity and poor circulation. Walking up and down the aisle and doing foot and leg exercises while seated can prevent it developing. Wearing compression tights or socks can also help to lessen your risk.

How can I get a cheap last-minute flight to New Castle?
Getting a cheap, spur-of-the-moment flight to New Castle is as easy as having some flexibility with your travel plans. Have some wiggle room with your travel dates, flight times and choice of carrier. If your destination has multiple airports, compare the prices of jetting into each of them for the best deal on your fare.
Where can I learn more about changing or canceling my flight to New Castle?
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.
