Do you have any tips for my flight to Plains?

  • What you pack in your carry-on can make the difference between a comfortable flight, and a restless one. Start with the important stuff, like your passport (or a valid ID) and your travel documents. Once they’re safely packed, throw in any medications you might need. Next? Consider your comfort factor. A neck pillow, earphones and a good book will help the time fly by while you’re soaring through the sky.
  • There’s a lengthy list of items you should not pack in your carry-on too. Flammables, explosives and sharps are strictly prohibited in the cabin — they often include box cutters, razor blades, aerosol cans and flares. Some sporting equipment, like tennis rackets and baseball bats, also generally can’t go in your hand luggage. Your airline’s website will have a full list of what you can and can’t take on board.

What to wear on a flight:

  • The aisles of a plane aren’t suitable for a fashion show. Layer up with comfy clothes and pack a sweater since it can get cool in the cabin on long-haul flights. Sneakers or other closed-toe shoes are ideal for longer journeys.
  • The condition known as deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting due to poor circulation and inactivity. Wandering up and down the aisle and doing leg and foot stretches while seated can prevent it developing. Wearing compression socks or tights can also help to lessen your risk.

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