If you have anyone that has mobility problems (elderly, young, injuries, etc) that would cause them to move slowly, call the airline and explain that you don't think you'd make the connection. I did that once on Delta when we were travelling with small kids and they had changed the schedule to a 30 minute connection in Atlanta. No problem. However, if you have nothing that would knowingly slow you down, be willing to take your chances. If it's a legal connection time, there's going to be nothing you can do to FORCE them to change your schedule.
