travel
Hi fourgolds,
for your journey to your home you go normally as extra crew member, you don't need a ticket for that and you are seated in 1st class if available, otherwise in business.
For you and your registered family members you can buy unlimited ID90 and Z-fare tickets.
Also you are entitled for 4 tickets free of charge in 1 year, also for you and your family.
Those are Y-class subload to business if space available; means it doesn't depend on the mood of ground staff to upgrade you, it's a must if there are empy seats.
As far as I know those tickets can also be used on other member airlines of the sky team, like Delta or Air France, some of my fellows have done that.
Regards,
