In the week before departure an agency produces more documents than in the rest of the departure combined. They all come from the same data but go to different parties, and each party needs something different. Sending one list to everyone means explaining it by phone every time.
The list the hotel needs
The hotel wants room numbers and the names staying in them. More than that only causes confusion: room type, group and mahram links are of no use to a hotel.
One detail is critical — names written in the Latin characters as they appear in the passport. The hotel registers check-in from the passport, and a mismatch means waiting at reception.
Then there is last-minute change. Rather than resending a hundred-room list, reporting only the changed rooms reduces both the error rate and the work on the other side.
The list the airline needs
The flight manifest is a different document entirely: name as printed in the passport, date of birth, passport number and expiry. Room information does not belong here.
PNR and seat numbers form the second half of that list. On group bookings seats come in bulk and the agency distributes them; keeping families together is resolved at this stage.
What reaches the passenger
Badges, baggage tags and door tags go directly to the passenger and their design serves a purpose. A badge carries the agency's phone number, the group number and the hotel name — the only source of information a lost passenger has in hand.
On a baggage tag the file number matters as much as the name. It is the fastest way to match a bag that got mixed up at the airport.
These need to be produced in bulk, in one pass. On a hundred-passenger departure, printing them one by one is the last time anyone can afford to lose in departure week.
The list the agency keeps
The roll-call list used at the airport differs from all of them: file number, name, phone and a checkbox. If the roll-call happens on a phone, the list has to be readable on a small screen.
Printing it on paper is still common and still sensible — airport internet is not reliable. But a paper list has to be entered back into the system afterwards, and that step is usually skipped.
One record behind all of them
That these documents look different should not mean they are stored separately. Produced from a single passenger record, one correction reaches every document at once.
Kept apart — the rooming list in a spreadsheet, the badge in a word processor — a single room change has to be corrected in three files and one gets forgotten. Most departure-day inconsistencies start here.
