How to get Thalys tickets on the thalys.com web site

Did you look at that specific train on April 10? Or is that a general "lowest fare" that sells out?

I wrote on your other post. Try the Eurostar website. Tickets are available for that train there, £61 each.

The Thalys.com site has the senior discount for $98 total. On the Raileurope:
Discounted tickets for youth, seniors and/or children are not available on this train. When discounted tickets are not available, travelers will be assigned as adults. Total: $142. Maybe this is the real reason the Thalys site blocks the sale?

Are those prices for one or both? Eurostar says the Senior price for that train is $85 each, $170 total. That is on the US site. I tried the French one but it wouldn't recognize Amsterdam as a starting point.

Actually it is 98 euros for 2 seniors (not dollars). I just worked through the site to the payment page, but of course I am not going to put in a credit card. It does not sound right they would let you get all the way to the payment page if that fare is not valid (and don't believe what RailEuroe says, they may not sell senior discount tickets but Thalys does offer them). So I would just try again, after notifying your bank, and if that doesn't work try calling Thalys during their daytime hours.

Go to the website of your bank, if there is one, and notify them by email AND phone of your intent to purchase overseas train tickets. Sometimes staff at a local bank doesn't always follow through with a request for overseas purchases. If yours is a local bank with no website, all you can do is ask to speak to an officer of the bank. You might also deal with the Eurostar.com site and purchase the tickets there, available at 120 days prior to travel, so the cheaper tickets might already be gone.

In addition to ensuring that the USA bank is aware before the transaction happens that it will occur - and that it will occur in France or Belgium or Netherlands. I say that because those are the countries that Thalys operates in and I don't know which their banks operate in. Clear your cookies - that may make a difference.

According to thalys.com, the cheapest advance purchase discount adult fare is €35. The anytime senior fare is €90.

€ 35 is the lowest fare, usually sells out within couple weeks of being released in the system on the most busy departures (early morning or late afternoon)
