Expedia France operates as part of Expedia Group's European network, which means you get the scale and inventory of a massive travel company but filtered through French interfaces and customer support. They're solid on flights and hotels, especially if you're mixing destinations or looking for something off the beaten track in France itself. The site handles package deals (flights with accommodation bundled together), last-minute escapes, and activities, so you're not just booking somewhere to sleep.
There's nothing particularly flashy about them compared to some rivals. They're reliable rather than charming. The French site can occasionally feel clunky if you're used to slicker interfaces, and their cancellation policies need reading carefully because they vary wildly depending on what you book and when. That said, if you're UK-based and planning to head somewhere in Europe, checking their France site alongside the main UK one sometimes throws up different pricing, especially for trips that originate from Paris or other French hubs.
They run regular offers on Martinique getaways and pet-friendly accommodation (which is genuinely useful if you're taking the dog along), and their activities section is decent for booking things once you're already somewhere rather than just the transport and bed.
