I tried to find the verb for the action of a person traveling along with a superior person (in rank or age) to help throughout the journey. I couldn't find out one. Example:
Jack _____ his mom to her business trip, just to manage reservations and to ease her trip.
Common verbs include accompanying, escorting, travelling-along. But these words do not really give the essence of help. Escort does, but it is not flexible enough.
The nouns include servant. Servant, in the present world sounds harsh on ears.
The example sentence could've been better, but I cannot think of one. To keep it clear, my search is related to travel. I hope answers from you. Thanks
