Do you have any tips for my flight to Princeton?

  • What you pack in your carry-on luggage can make the difference between a comfortable flight, and one that leaves you tired. Start with the most important stuff, like a valid ID (like your passport) and your travel documents. Once they’re safely packed, toss in any medications you might need. Next? It’s all about comfort. A neck pillow, noise-canceling headphones and the latest bestseller will help the time fly by while you’re soaring above the clouds.
  • Remember that there’s also a list of prohibited items for your hand luggage which differs between airlines. Generally, avoid carrying anything flammable, explosive or sharp. This includes things like box cutters, razor blades, aerosol cans and flares. Sporting equipment like baseball bats, and objects that could harm passengers, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

  • The aisles of a plane aren’t the place for a fashion show. Layer up with comfy clothes and pack a pullover since it can get cool in the cabin during long-haul flights. Sneakers or enclosed, flat shoes are perfect for longer journeys.
  • Consider wearing compression socks or tights to reduce the risk of deep vein thrombosis (DVT). This condition is a result of blood clotting that can be caused by extended periods of sitting, especially on long flights. Performing foot and leg exercises in your seat or walking around the cabin will help improve your circulation.

How can I get a cheap last-minute flight to Princeton?
Getting a cheap, spur-of-the-moment flight to Princeton is as easy as being flexible with your travel plans. Have some leeway when it comes to your choice of airline, flight times and travel dates. If your destination has a few airports, compare the prices of jetting into each of them for the best airfare deals.
Where can I learn more about changing or canceling my flight to Princeton?
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.
