The detail to resolve first
An infant adds more than one passenger to the planning checklist: an appropriate restraint, bags and possibly a stroller. State whether you intend to bring your own seat. Do not send medical details; describe practical needs and ask which arrangements can be confirmed.
Prepare a workable enquiry
State the children’s ages and request the appropriate child seats explicitly. Include the stroller’s folded size and ask for confirmation of the seat arrangement.
Check the written arrangement
Ask which parts of the itinerary are included, how waiting is handled and what to do if the schedule changes. Identify any tickets, guiding, specialist assistance or extra stops that require separate arrangements.
Keep the written confirmation available to the passenger. An enquiry or a WhatsApp conversation is not a confirmed reservation until the specific journey has been accepted.
