Seeking an update on an earlier post of mine due to delayed/cancelled travel plans. Upcoming trip LHR-MAD-SVQ, with two (slightly) older parents. Flying on IB3175 (A330) from LHR to MAD, arriving T4S at 14:15. Connecting flight departs to Seville from T4 at 16:00, so 1hr45m transfer time. This is a single ticket, booked direct with Iberia, so bags checked through? Is this transfer achievable? If delayed, I believe there is a later flight, would this be Iberia's responsibility or ours? Thanks
