I use an actual travel agent with a real office, in Ogallala. In cases where she canโt help us (like buying rail tickets for our trip to Germany and Poland or our trip to Churchill), I call the transport company in question.
Computer algorithms are useful but they can fall apart in extreme situations. So sometimes the programmers needs to add a condition to the formula that specifies the result cannot exceed $x or fall below $y. OTOH, the programmers here are probably not given any guidance and no one has directed them on min/max bounds to incorporate.
