Ticketing is where a programme either starts smoothly or begins with an argument at a counter. Three details account for most of the problems we see.
Names must match the passports
Air and rail tickets in China are issued against the passport, and a mismatched name is not a small administrative issue — it can stop a passenger boarding. Collect passport details at the point of booking, check the spelling of every name, and treat any change as a rebooking rather than a correction.
Air and rail are separate systems
Domestic air and high-speed rail are booked, ticketed and changed in different systems, with different rules. A group that travels by both needs two sets of passenger records and two sets of deadlines. Build the programme so the two do not have to be modified on the same day.
Schedule changes are normal — plan the buffer
Airline schedules in China are adjusted seasonally, and rail inventory opens on its own timetable. A programme that assumes the flight will land at the scheduled minute has no room for a delay. Where the itinerary is tight, add a buffer the group can absorb rather than a connection it cannot miss.
What good looks like
One passenger list, verified against passports, held by the operator. Confirmed fares in writing before issuance. A named person monitoring schedule changes while the group is travelling. None of it is glamorous; all of it is what keeps the first morning on schedule.
