Expedia Spain operates out of expedia.es and does what you'd expect from the Expedia brand: flights, accommodation, car hire, and package holidays. The catalogue is biggest for European destinations, which is handy if you're planning a city break or summer getaway within striking distance. They've made a push on holiday rentals and flexible booking in recent years, partly because people got burned during the pandemic and now want the option to back out without losing everything.
What sets them apart slightly is their rewards programme. If you book enough, you rack up points that knock money off future trips. It's not revolutionary, but it does add up over time if you're a regular traveller. Last-minute deals are their bread and butter, especially for hotels, so if you're flexible with dates you can find genuine savings.
The Spanish site can feel a bit clunky compared to the UK version, but the prices are often identical. Customer service exists, though don't expect it to be quick. Most of your interaction will be self-service, which is fine if things go smoothly and frustrating when they don't.
