Do you have any tips for my flight to Castle Rock?

  • Get your vacation off to an excellent start by being prepared. Pack your passport, travel documents and any medications you need first. Next, think about downloading a few blockbuster movies on your tablet for a guiltless binge session. Or, bring that fantasy bestseller you’ve been wanting to read. Lastly, a few snacks and a neck pillow will help make the trip as comfortable as possible.
  • There’s also a list of prohibited items for your hand luggage which can differ between airlines and routes. Generally, avoid bringing anything explosive, sharp or flammable. This includes things like utility knives, razor blades, aerosol cans and flares. Sports equipment like baseball bats, and objects considered weapons, such as batons and swords, are also banned from the cabin.

What to wear on a flight:

  • The aisles of a plane aren’t the place for a fashion show. Layer up in comfortable clothes and bring a hoodie as it can get cool in the cabin on long-haul flights. Sneakers or other closed-toe shoes are the best type of footwear for longer journeys.
  • Lessen your risk of developing deep vein thrombosis (DVT), a blood clotting condition which can be caused by sitting for extended periods, by regularly walking around the cabin. You can also do some gentle lower limb 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 Castle Rock?
The key to booking a cheap last-minute flight to Castle Rock is to stay flexible. You can nab an unbeatable deal if you’re not tied to particular carriers, travel dates and flight times. Also compare the prices of flying into and out of nearby airports if that’s an option.
Where can I learn more about changing or canceling my flight to Castle Rock?
