Yes, they can check your bag to the final destination. One time LX held my checked bag for a connection time of 23 hours and 45 minutes.
is this still the case? For a ICN-ZRH-EWR with overnight layover ~18 hours. Really don't want to be required to retrieve and recheck bags in ZRH. With USA being the final destination, does that have any impact?
Thanks for any recent experiences.
