For example, Indian Citizen on Indian Passport flying via FRA to Atlanta on a ticket of AI to DL. If AI & DL do not have an interline agreement or the traveler doesn't have the correct visa to enter Germany (EU) to get bags and recheck. Ideally airlines on 1 itinerary are supposed to interline but some itineraries are put together outside the standard to get desired routing.
