Do you have any tips for my flight to San Sebastián?
Depending on where you're coming from, your flight to San Sebastián could be no sweat at all or it could go on forever. Here are some useful tips that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

  • First of all, pack in your passport, important documents, wallet and daily medications. Next, you'll want some in-flight entertainment to while away the time. A juicy novel and a laptop filled with your favourite movies are good options. If you plan to take a short nap, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, make room for a toothbrush and some deodorant so you'll arrive at your destination looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects hiding in the bottom of your carry-on luggage. Other restricted items include flammable or explosive products, such as bleach and fuel, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Layer your clothing and opt for shoes that are enclosed, flat and easy to pull on and off.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Reduce the risks by drinking water, keeping your ankles and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to San Sebastián?
It's easy — be prepared. We've rounded up some helpful hints for a fuss-free trip through airport security. Look out San Sebastián, here you come:

  • Airport security personnel first need to make sure that you have a valid ID and matching travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online in no time.
  • Remember to remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and heavier-style shoes are often subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board and will be confiscated.
