Eurostar is taking 25% off Standard and Plus tickets from London to Paris, Brussels, Lille, Amsterdam and Rotterdam if you book by 22:59 BST tonight, 8 June, for travel from 24 June to 23 September.
That is a cleaner public discount than Eurostar usually gives. Most of the time you are hunting scattered low fares and hoping your dates line up. This one is simpler, and it covers proper summer travel rather than a random off-peak pocket.
The useful catch is timing. You need to book tonight, adult tickets only are included, and a run of late-June and July peak dates is excluded across the main routes. Amsterdam and Rotterdam also have a few extra engineering-work blackout dates, so check your exact dates before you pay.
What is included?
- 25% off Eurostar Standard and Eurostar Plus tickets each way
- Routes from London St Pancras to Paris, Brussels, Lille, Amsterdam and Rotterdam
- Booking window: from 09:00 BST on 2 June to 22:59 BST on 8 June
- Travel window: 24 June to 23 September
- Adult tickets only
- Checked on 8 June
We like this because summer Eurostar fares can climb fast once weekends and school-holiday dates start filling up. A straight 25% cut is easier to use than points offers, subscription perks or last-minute roulette, especially if you already know roughly when you want to go.
If you want absolute freedom on dates, the exclusions matter. If you want a summer city break and your dates are flexible enough to work around the blocked days, this is a strong rail deal.
How to book
Book direct with Eurostar. Search your route and dates, make sure the fare shown reflects the sale, and check the total before paying. For Amsterdam and Rotterdam, double-check the engineering-work dates because some services are not running.
