Flying Winemaker

My mother will be flying from Durham to Bordeaux via Schiphol this month: arrive Schiphol 12.35, depart 14.20. Any tips please on how to make the connection go smoothly? Does she need to go to a Transfer desk and are these clearly signed? Will she need to change terminal?

She is a sprightly 77 year old and doesn't require special assistance.

Thanks for any advice!
