Do you have any tips for my flight to Glen Carbon?

  • Wherever you’re heading, flying can be a relaxing experience if you’re prepared. Firstly, pack your passport (or a valid ID), travel documents and medications. Next, toss in a little extra in-flight entertainment to help the time fly by. A good book and a tablet filled with your favorite series are some fantastic options. If you plan on getting some sleep, a memory-foam neck pillow and earplugs will also come in handy.
  • There’s a list of items you should not pack in your carry-on bag too. Sharps, flammables and explosives are strictly prohibited in the cabin — they often include knives of any sort, flares and aerosol cans. Some sporting equipment, like baseball bats and tennis rackets, 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 bring on board.

What to wear on a flight:

  • Go for comfort over fashion when flying. Layer up and wear natural fabrics since they allow air and moisture to pass through and keep you cool. Cabins can get colder on longer journeys, so pack a pullover and always wear sneakers or enclosed shoes.
  • Consider wearing compression socks or tights to help prevent deep vein thrombosis (DVT). This condition is a result of blood clotting that can be caused by prolonged periods of sitting, especially on long-haul journeys. Performing leg and foot exercises in your seat or wandering around the cabin will help improve your circulation.

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