Do you have any tips for my flight to Casco?

  • What you pack in your carry-on baggage can make the difference between a comfortable flight, and one that leaves you drained. Start with the most important stuff, like your passport (or a valid ID) and your travel documents. Once they’re safely packed, put in any medications you might need. Next? It’s all about comfort. Earphones, a quality neck pillow and a good book will help the time fly by while you’re in the air.
  • There’s a list of items you should not pack in your carry-on bag too. Sharps, explosives and flammables are strictly prohibited in the cabin — they can include box cutters, razor blades, aerosol cans and flares. Some sporting equipment, like martial arts weapons and baseball bats, also generally can’t go 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 short or long-haul, layering up is key to a comfy flight. Opt for loose, natural fabrics that will keep you cool and bring a pullover to cope with any in-flight cabin temperature changes. Your feet will be happy in a pair of flat shoes or sneakers.
  • Reduce your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for lengthy periods, by regularly walking around the cabin. You can also do some gentle foot and leg exercises in your seat. If you’re at higher risk of developing DVT, consider wearing compression socks.

How can I get a cheap last-minute flight to Casco?
If you want to nab a cheap last-minute flight to Casco, it’s important to be flexible. If you can, have a bit of wiggle room with the dates you can travel. It will also help to have a degree of flexibility with your departure and arrival points, airline choice, flight times and potential layovers or stops.
Where can I learn more about changing or canceling my flight to Casco?
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.
