I needed help on one trip flying Air France and Delta. I requested wheel chair assistance and they take you to each gate, fast and efficient. they will also board you first. Your mom should do fine. You can call the airline before her trip and request this help. When she gets off the first plane someone will be waiting just outside the airplane door to transfer her.
