Eurostar Double & Triple points promo has just arrived in my inbox.
Book by 23 Dec
Travel between 15 Jan and 15 Apr on UK or Continental routes.
– Eurostar Standard gets double points, so 2.4 points per £ instead of 1.2
– Eurostar Plus (Standard Premier in old money) gets triple points, so 3.6 per £
I don’t know if the tier bonuses are doubled/ tripled too. Existing bookings don’t count.
I think a fair valuation of Eurostar points ~8p each, so this is close to a 29% rebate in Plus.
I don't see any rules in the T&Cs which says you have to book direct, so presumably you could book with Uber. The offer does appear to be limited to people who are already registered with Club Eurostar, and opted into promotions.
