I thought they were available only 4 months out, but when I checked today for tickets on Sept. 22, they were there for purchase. Can you now book up to 5 months in advance?
Hi Sarah, Someone reported this on the tripadvisor London Forum recently. It seems that the U.S. Eurostar site has tickets way more than four months in advance now (someone bought tickets for December. However, if you use either the UK or France or Belgium site, you can only buy 4 months out. I don't think anyone knew why this was or if this had changed recently.
