Do you have any tips for my flight to Knoxville?

  • What you pack in your hand luggage can be the difference between a comfortable flight, and a not-so-great one. Start with the must-haves, such as 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 comfort. A quality neck pillow, earplugs and a juicy novel will help the hours fly by while you’re soaring above the clouds.
  • You’ll also want to check with your airline regarding what you can’t bring on board your flight. Batons, swords, box cutters, razor blades and knives are among the prohibited items. Anything sharp, flammable or explosive is generally not allowed in your carry-on baggage. Don’t forget to pack any sports equipment like tennis rackets or baseball bats only in your checked luggage.

What to wear on a flight:

  • Whether traveling long or short-haul, wearing layers will help you stay comfortable. Choose loose, breathable fabrics that will keep you cool and bring a pullover to cope with any in-flight temperature changes. Your feet will be happiest in a pair of closed-toe shoes or sneakers.
  • Consider wearing compression tights or socks to reduce the risk of deep vein thrombosis (DVT). This blood clotting condition can be caused by extended periods of sitting, especially on long-distance journeys. Doing foot and leg stretches in your seat or wandering around the cabin are great ways to improve your circulation.

How can I get a cheap last-minute flight to Knoxville?
The key to finding a cheap last-minute flight to Knoxville is to stay flexible. You can score a fantastic deal if you’re not tied to specific airlines, flight times and travel dates. Also compare the prices of flying out of and into nearby airports if that’s an option.
Where can I learn more about changing or canceling my flight to Knoxville?
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.
