Do you have any tips for my flight to St. Charles?

  • Get your vacation off to the best start possible by being prepared. Pack the important stuff — like travel documents, your passport and any medications you need — first. After that, think about downloading a few movies on your tablet or phone for a sans-guilt binge session. Or, toss in that bestseller you’ve been saving for a rainy day. Lastly, a snack to nibble on and a good neck pillow will go a long way to making your flight as comfy as possible.
  • 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 can include knives of any sort, flares and aerosol cans. 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 a comfortable flight. Choose loose, natural fabrics that will keep you cool and pack a sweater for any changes in cabin temperatures. Keep your feet happy in a pair of closed-toe shoes or sneakers.
  • The condition known as deep vein thrombosis (DVT) is a risk on long-distance flights. It’s the result of blood clotting caused by poor circulation and inactivity. Wandering up and down the aisle and doing foot and leg exercises while seated can prevent it developing. Wearing compression tights or socks also helps reduce your risk.

How can I get a cheap last-minute flight to St. Charles?
Securing a cheap, last-minute flight to St. Charles is as easy as having some flexibility with your travel plans. Have some wiggle room when it comes to your choice of airline, travel dates and flight times. If your destination has multiple airports, compare the prices of flying into each of them for the best deal.
Where can I learn more about changing or canceling my flight to St. Charles?
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.
