Interesting. The "family supplement" feels like it could use some work though. You pay €110 extra, and up to 4 of your children (<15 years old) can travel wit

Interesting. The "family supplement" feels like it could use some work though. You pay €110 extra, and up to 4 of your children (<15 years old) can travel with you. But your partner isn't included...they would also have to pay the extra if they ever planned on being with the kids, and without you. And the kids have to buy a ticket if traveling alone. It's not expensive per se, but it seems like a narrow set of uses.
