Do you have any tips for my flight to Castleknock?

  • What you pack in your hand luggage can mean 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, toss in any medications you might need. Next, think about comfort. Earplugs, a neck pillow and a juicy bestseller will help the time fly by while you’re soaring above the clouds.
  • There’s a lengthy list of items you shouldn’t pack in your carry-on baggage too. Flammables, explosives and sharps are strictly prohibited in the cabin — they often include box cutters, razor blades, flares and aerosol cans. 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 a full list of what you can and can’t bring on board.

What to wear on a flight:

  • Go for comfort rather than fashion when flying. Dress in layers and wear natural materials since they allow moisture and air to pass through and keep you cool. Cabins can get colder on longer journeys, so bring a sweater and always wear sneakers or flat, closed-toe shoes.
  • The condition called deep vein thrombosis (DVT) is a risk on long-distance flights. It’s the result of blood clotting caused by inactivity and poor circulation. Wandering up and down the aisle and doing leg and foot exercises while seated can prevent it developing. Wearing compression socks or tights also helps reduce your risk.

How can I get a cheap last-minute flight to Castleknock?
The key to tracking down a cheap last-minute flight to Castleknock is to remain flexible. You can nab an excellent deal if you’re not tied to specific airlines, flight times and travel dates. Also compare the prices of flying into and out of alternative airports if that’s a possibility.
Where can I learn more about changing or canceling my flight to Castleknock?
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.
