I dont have much pity for those that dont plan so I would still find it rude even if an FA asked if I could move in such a situation unless the flight was rather late which apparently wasnt the case. If you have a tight connection you should select a seat that allows you the fastest time to get off the plane when booking your ticket. OR leave a longer layover Now if there are delays that would be understandable but Someones poor planning doesnt constitute an emergency on my part. If she had a 15 minute connection time she booked 2 different itineraries
