Do you have any tips for my flight to Louisville?

  • What you pack in your cabin baggage can make the difference between a comfortable flight, and one that wears you out. Start with the most important things, such as your passport (or a valid ID) and your travel documents. Once they’re safely packed, put in any medications you might need. Next? Consider your comfort factor. Earplugs, a quality neck pillow and a good book will help the hours fly by while you’re in your seat.
  • There’s a lengthy list of items you shouldn’t pack in your carry-on too. Flammables, sharps and explosives are strictly prohibited in the cabin — they often include aerosol cans, flares, box cutters and razor blades. Some sporting equipment, like martial arts weapons and baseball bats, are also not allowed in your hand luggage. Your airline’s website will have all the details about what you can and can’t bring on board.

What to wear on a flight:

  • Whether traveling long or short-haul, layering up is key to staying comfortable. Wear loose, breathable fabrics that will keep you fresh and pack a pullover to cope with any in-flight cabin temperature changes. Your feet will be happy in a pair of sneakers or closed-toe shoes.
  • The condition known as deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting caused by inactivity and poor circulation. Wandering up and down the aisle and doing foot and leg stretches while seated can help prevent this developing. Wearing compression socks or tights can also help to lessen your risk.

How can I get a cheap last-minute flight to Louisville?
If you want to nab a cheap, spur-of-the-moment flight to Louisville, flexibility is key. If you can, have a bit of wiggle room with your travel dates. It’s also a good idea to keep your options open with your departure and arrival airports, choice of carrier, flight times and potential stops or layovers.
Where can I learn more about changing or canceling my flight to Louisville?
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.
