A few questions which I cannot find the answer to, and am hoping you awesome people can help.
1: We have set dates for Darmstadt to Cologne, then from Cologne to Brussels. Can we use the 9€ ticket on either of those routes? I'm thinking not, but figured I'd ask.
2: Is 9€ good on a trip from FRA to Darmstadt?
3. What site can I use to determine if a route qualifies for the 9€ tix?
4: If a trip is not eligible for the discounted tix, is it cheaper to buy tix in advance? If so, how much cheaper is it versus how far out your dates are?
Thanks for the info!
