Do you have any tips for my flight to Castro Urdiales?
No matter where you're coming from, flying can be a pleasant experience if you're well prepared. We've made a list of handy travel tips that will get your Castro Urdiales holiday started on the right note. What to pack in your hand luggage:

  • Travelling on a plane can be a comfortable experience if you pack the right things. First of all you'll need toiletry items, such as deodorant and a toothbrush, a spare pair of socks and a magazine or two. Secondly, find room in your carry-on bag for your mobile phone, a charger, any medications and perhaps a neck pillow as well. Last, but definitely not least, don't forget to take your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a Swiss Army knife hiding in one of the compartments of your carry-on luggage. Other prohibited items include flammable or explosive products, such as bleach and fuel, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on board. Loose clothing is a sensible choice, as are flat, slip-on shoes.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To lower your risk on board, drink lots of water, consider wearing compression socks or tights and keep your legs and feet moving.

How to get through airport security fast when flying to Castro Urdiales?
As savvy travellers know, the secret is to be organised before you get to the security gate. That way, you'll be stepping onto that plane to Castro Urdiales in the blink of an eye. Follow these tips and get your trip off to a spectacular start:

  • Security personnel first need to see that you have a valid passport and boarding pass before anything else. Keep them close by.
  • Time to strip down. Well sort of. Your belt, jacket, keys and other items in your pocket, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them before your turn arrives.
  • Electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry, you'll be back online soon enough.
  • Any liquids or gels, such as perfume or hairspray, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed in the cabin.
