I'm booking a *A reward flight through BMI route LHR-FRA-LAX in mid november the LHR flight arrives at 0900 and the FRA flight departs at 1015. Is 1 hr 15 enough for the connection at FRA given that the LH website suggests that 2hrs min is needed? I cannot just book the FRA-LAX flight on its own using a different flight from London the day earlier because of married segment issue - this ticket can only be booked on the full route.

My question is if we miss our flights will LH put us on a later/other carrier the same day? And is this connection doable.

Thanks
