Known Before a Trip Exists

Why these four come first

None of them depends on anything being booked. Somebody thinking about a journey in three months can answer all four today, and a desk holding all four can already tell whether the job is ordinary or unusual before a single operator is asked.

That matters more than it sounds. A request that arrives complete in this moment can be placed the same day a ticket appears, instead of starting from nothing.

What goes wrong in this moment

Not error. Looseness. An address given as a district, a luggage count given as a shrug, a telephone number left blank because the form said it was optional.

Every one of those is reasonable at the time and every one of them costs somebody later, which is why each entry says plainly what an operator cannot answer without it.

The four

1. Known before a trip existsThe two ends, written as addressesA journey has two ends and the desk needs both of them as places, not as districts. It is the first thing asked and the one most often given loosely.
2. Known before a trip existsHow many people the desk has to seatA count, not a vehicle. The desk writes down how many people are traveling and lets the operator decide what turns up.
3. Known before a trip existsWhat has to go in with themLuggage is the quiet reason a booking fails at the curb. The desk records what has to travel and hands the number on without rounding it down.
4. Known before a trip existsA number a callback actually reachesA quote is read back by voice more often than it is read on a screen, and a number that goes to a full mailbox is the same as no number at all.
