I started this discussion back in Feb/March. However, I don't remember ever getting a good answer.

I'm making an international connection on one ticket which involves two different carriers and three different countries.

When I'm checking in for my first segment,
1.) Will my luggage be checked to the final destination?
2.) Do I receive boarding passes for both segments?

Second scenario, same two segments except they are on seperate tickets.
1.) Can I request that my luggage be checked to the final destination?
2.) Can I check-in for the second segment when I'm checking in for my first segment?

If not, does that mean I will have to depart airside by going thru immigration/customs at the connecting point, check in for the second segment, and then re-enter airside by going thru immigrations again?

Thanks for your help.
